	BOOTP, Bootstrap Protocol Overview (RFC 951 1542)
		BOOTP provides a means to notify a host of its assigned IP address, the IP address of a boot server host, and the name of a file to be loaded into memory and executed.
		BOOTP is an alternative to RARP, which operates at the Data Link Layer for LAN only.
		BOOTP is defined by IETF (http://www.ietf.org) RFC 951 and 1542.

		BOOTP provides a means to notify a host of its assigned IP address, the IP address of a boot server host, and the name of a file to be loaded into memory and executed [1].
		Unfortunately, the 'giaddr' field may contain the address of a BOOTP relay agent that is not itself an IP router (according to [1], Section 8, fifth paragraph), in which case, it will be useless as a first-hop for TFTP packets sent to the server (since, by definition, non-routers don't forward datagrams at the IP layer).
		It is incorrect for a relay agent implementation to simply forward a BOOTP message "straight through like a regular packet." This relay-agent functionality is most conveniently located in the routers which interconnect the clients and servers, but may alternatively be located in a host which is directly connected to the client subnet.

	BOOTP
		BOOTP (Boot Protocol) may be used to boot remote computers over a network.
		BOOTP messages are encapsulated inside UDP messages and therefore its requests and replies are forwarded by routers.
		BOOTP is defined by RFCs 951 and 1542.

	BOOTP (Site not responding. Last check: 2007-11-03)
		BOOTP stands for Boot Protocol and is defined by RFC 951 and RFC 1542.
		BOOTP (Boot Protocol) may be used to boot remote computers over a network so they can get their IP address automatically and the network location of an operating system boot image.
		BOOTP allows remote workstations to get an IP address prior to loading an operating system and allows diskless workstations to operate by loading their operating system over a network.

	[No title]
		Overview This RFC describes an IP/UDP bootstrap protocol (BOOTP) which allows a diskless client machine to discover its own IP address, the address of a server host, and the name of a file to be loaded into memory and executed.
		The BOOTP packet is enclosed in a standard IP [8] UDP [7] datagram.
		The server sends replies using 'BOOTP client' as the destination port; depending on the kernel or driver facilities in the server, this may or may not be a broadcast (this is explained further in the section titled 'Chicken/Egg issues' below).
	www.ietf.org /rfc/rfc951.txt (3703 words)

	BOOTP
		In computing, BOOTP, short for Bootstrap Protocol, is a UDP network protocol used for a network client to get the IP address automatically.
		The BOOTP servers assign the IP-address from a pool of addresses to each client with a certain lease time.
		Historical UNIX-like diskless workstations tended to use BOOTP to obtain their IP address as well as the name and location of their boot image or kernel.

	Secure Design - BootpNamer
		Bootp Namer can update a number of things on the workstation including the Macintosh name, Owner name, and login names used for AppleShare servers.
		To use Bootp with MacTCP, the control panel should be set to obtain the IP address from a server.
		Bootp namer can make management of Macintosh computers easier when each of the computers is configured in a similar manner.

	BOOTP (Site not responding. Last check: 2007-11-03)
		Bootstrap protocol (BOOTP) is a TCP/IP protocol that allows the Network Station to request an IP address and the location of the base code file from a server.
		BOOTP then returns a reply that assigns the IP address for the Network Station and the name and location of the base code file.
		Because BOOTP assigns IP addresses statically (fixing an IP address according to a computer's MAC address and then recording this assignment), it is less versatile than DHCP.

	Bootstrap Protocol, BootP, DHCP
		Bootp however uses IP/UDP (port 67 for the server destination port, and port 68 for the client source port) and can cross routers.
		If the client is on the same LAN as the Bootp server, then the Bootp server will respond to the broadcast, by using the MAC address of the client, and the IP address will be given to the client.
		No Bootp server exists locally so the router R1, which is configured to forward Bootp/DHCP requests, sends a unicast with the source IP address of it's LAN interface on which it received the initial broadcast.

	bootpLib
		This routine performs a BOOTP message exchange according to the process described in RFC 1542, so the server and client UDP ports are always equal to the defined values of 67 and 68.
		To obtain these parameters, the BOOTP server must support the vendor-specific options described in RFC 1048 (or its successors) and the corresponding parameters must be specified in the BOOTP server database.
		The BOOTP request issued during system startup with this routine attempts to retrieve a subnet mask for the boot device, in addition to the host and client addresses and the boot file name.

	The TCP/IP Guide - BOOTP Message Format
		BOOTP messages contain a considerable number of fields, so the message format is rather large.
		The BOOTP standard specifies that the use of UDP checksums is optional.
		Since BOOTP messages are only 300 bytes in length, under the minimum MTU required for all TCP/IP links, this is not normally an issue.

	BOOTP - BOOTstrap Protocol
		The BOOTP host, if configured, provides the dumb node with an IP address, the IP address of a load host (usually itself), and the name of the download file.
		The dumb node needs only know its own hardware address, as this is what the BOOTP server uses to decide whether it can help the node and what information to provide.
		The bootp protocol allows a client machine to discover its own IP address, the address of a server host, and the name of a file to be loaded into memory and executed.

	BOOTP (BOOTstrap Protocol) (Linktionary term)
		BOOTP is an Internet protocol that can provide network configuration information to diskless workstations, or other workstations if necessary, on a local network.
		BOOTP obtains an IP address, a gateway address, and a name server address.
		Information returned by the BOOTP server to the booting computer includes its IP address, the IP address of the server, the host name of the server, and the IP address of a default router.

	Fusion BOOTP - Bootstrap Protocol
		The Fusion BOOTP protocol is used by a client machine to locate its IP address and network mask.
		It also may be used to locate a server host and the name of a file to be loaded (bootstrapped) into the client machine for execution.
		Fusion BOOTP source code is compliant with RFCs 951 and 1542.

	BOOTP
		Bootstrap protocol, BOOTP, is the recommended way to establish communications from the host to the printer in an internet protocol environment.
		For the preceding examples, bootpd would be located in /etc. If there is a mismatch between the actual location and the specified location, either move the bootpd binary or change the /etc/rc.local file.
		The port numbers for BOOTP listening and replying must be set in the /etc/services file.
	www.office.xerox.com /userdoc/PShare3/bootp2.htm (731 words)

	Bootp and DHCP
		In the case of Bootp, the server must first be configured with an entry that has the MAC address of the hub.
		Thus, if a DHCP or Bootp server is not available or accessible to the hub when DHCP/Bootp is first configured, the hub may not immediately receive the desired configuration.
		That is, the Bootp server replies to a request with a configuration previously stored in the server and designated for the requesting device.

	How BOOTP Works
		The Bootstrap Protocol (BOOTP) allows a client system to discover its own IP address, the address of a BOOTP server, and the name of a file to be loaded into memory and executed.
		Figure 5-1 “Bootrequest Relay Example” shows an example of a bootrequest that is relayed from server A to server B to server C. Server C finds the client's boot information in its database, and sends the bootreply back to server A. Server A then sends the bootreply to the client.
		NOTE: BOOTP clients can be booted over a gateway; however, the BOOTP server with the relay information for the client must be on the same side of the gateway as the client.

	What is BOOTP? - a definition from Whatis.com - see also: Bootstrap Protocol
		- BOOTP (Bootstrap Protocol) is a protocol that lets a network user be automatically configured (receive an IP address) and have an operating system booted (initiated) without user involvement.
		The BOOTP server, managed by a network administrator, automatically assigns the IP address from a pool of addresses for a certain duration of time.
		BOOTP is the basis for a more advanced network manager protocol, the Dynamic Host Configuration Protocol (DHCP).

	Configuring Bootstrap Protocol (BOOTP) service (Site not responding. Last check: 2007-11-03)
		A BOOTP client uses the command bootp(1Mtcp) to broadcast a request for information from any BOOTP server that has been configured to respond to it on the local subnet.
		If a BOOTP server has not been configured to reply on the local subnet, a local machine can be configured as a BOOTP gateway which uses bootpgw(1Mtcp) to forward a request to a server or gateway on another subnet.
		When a BOOTP server receives a request from a client for which it holds configuration information, it uses the bootpd(1Mtcp) daemon to reply directly to the client, possibly via a BOOTP gateway, without broadcasting.

	Bootstrap Protocol - Wikipedia, the free encyclopedia
		In computing, BOOTP, short for Bootstrap Protocol, is a UDP network protocol used by a network client to obtain its IP address automatically.
		BOOTP enables 'diskless workstation' computers to obtain an IP address prior to loading any advanced operating system.
		DHCP (Dynamic Host Configuration Protocol) is a more advanced protocol based on BOOTP, but is far more complex to implement.

		BOOTP clients and DHCP servers The format of DHCP messages is defined to be compatible with the format of BOOTP messages, so that existing BOOTP clients can interoperate with DHCP servers.
		Since BOOTP clients may not be prepared to receive automatic addresses, the decision to allow a DHCP server to return automatic addresses must be under the control of the system administrator.
		DHCP clients and BOOTP servers A DHCP client MAY use a reply from a BOOTP server if the configuration returned from the BOOTP server is acceptable to the DHCP client.

	DHCP FAQ (via CobWeb/3.1 planetlab2.cs.unc.edu) (Site not responding. Last check: 2007-11-03)
		The main difference is that BOOTP was designed for manual pre-configuration of the host information in a server database, while DHCP allows for dynamic allocation of network addresses and configurations to newly attached hosts.
		There is an issue with trying to use DHCP (or BOOTP) and VLANs at the same time, in particular, with the scheme by which the VLAN-capable network determines the client's VLAN based upon the client computer's source IP address.
		Typically you have to enable it on the interface to the subnet to be served and have to configure it with the IP address of the DHCP or BOOTP server.

	Booting with BOOTP Page (Site not responding. Last check: 2007-11-03)
		BOOTP is a network service program (refer to RFC 951, RFC 1048, and RFC 1084 for specific details) running on your host computer that listens for startup or boot requests.
		BOOTP may be used to load the configuration file (containing Setup Mode values) or load only the @workStation boot file (containing the server code) or both.
		These entries and values, along with any other BOOTP fields your system may use, are retrieved from the bootp table and sent to the @workStation in the bootp response.

	OIT DHCP and BootP Services (via CobWeb/3.1 planetlab2.cs.unc.edu) (Site not responding. Last check: 2007-11-03)
		There is no concept of a "lease" in BootP; your device may use the information it obtains via BootP until it is restarted (or its IP stack is unloaded).
		OIT Mobile IP Service is not available to BootP clients, because without the concept of a "lease", there is no reasonable way for the server to reclaim IP addresses after they have been used.
		If that were to happen, and if one (or more) of your interfaces used DHCP or BootP to obtain their IP addresses, having one interface steal the other's IP address is likely to result in your device being declared insuitable for using DHCP and BootP on the campus network.
