Baker Standards Track [Page 13] RFC1812 Requirements for IP Version 4 Routers June 1995 The second part of the principal is almost as important: software on hosts or other routers may contain deficiencies that make it unwise to exploit legal but obscure protocol features.
The router-id is one of the Baker Standards Track [Page 25] RFC1812 Requirements for IP Version 4 Routers June 1995 router's IP addresses (a router is required to have at least one IP address).
Baker Standards Track [Page 26] RFC1812 Requirements for IP Version 4 Routers June 1995 (4) When a host running embedded router code is concurrently used for other services, the Operation and Maintenance requirements for the two modes of use may conflict.

RFCs can be obtained on the Internet from the RFC Editor [1], the IETF [2], or many other sites, principally using the Web, but also through anonymous FTP, gopher, and other Internet document-retrieval systems.
RFC 2047 specifies a standard way of encoding non US-ASCII characters into a string that identifies both the character set to use and the actual characters.
RFC1812 Requirements for IP Version 4 Routers June 1995 4.2.2.7 Fragmentation: RFC 791 Section 3.2 Fragmentation, as described in [INTERNET:1], MUST be supported by a router.
RFC1812 Requirements for IP Version 4 Routers June 1995 4.2.2.8 Reassembly: RFC 791 Section 3.2 As specified in the corresponding section of [INTRO:2], a router MUST support reassembly of datagrams that it delivers to itself.
RFC1812 Requirements for IP Version 4 Routers June 1995 4.2.3 SPECIFIC ISSUES 4.2.3.1 IP Broadcast Addresses For historical reasons, there are a number of IP addresses (some standard and some not) which are used to indicate that an IP packet is an IP broadcast.
Baker Standards Track [Page 57] RFC1812 Requirements for IP Version 4 Routers June 1995 DISCUSSION A router itself may receive a Source Quench as the result of originating a packet sent to another router or host.
Baker Standards Track [Page 58] RFC1812 Requirements for IP Version 4 Routers June 1995 A router SHOULD have a configuration option that, if enabled, causes the router to silently ignore all ICMP echo requests; if provided, this option MUST default to allowing responses.
If they are implemented then: Baker Standards Track [Page 59] RFC1812 Requirements for IP Version 4 Routers June 1995 o The ICMP Timestamp server function MUST return a Timestamp Reply to every Timestamp message that is received.

This RFC is intended to alert the IP community about the performance limitations of MD5, and to suggest that alternatives be considered for use in high speed IP implementations.
The IAB suggests that while RFC 1597 establishes reserved IP address space for the use of private networks which are isolated and will remain isolated from the Internet, any enterprise which anticipates external connectivity to the Internet should apply for a globally unique address from an Internet registry or service provider.
This is a modification to the procedures of RFC 1602 and 1603.
Baker Standards Track [Page 55] RFC1812 Requirements for IP Version 4 Routers June 1995 4.3.2.8 Rate Limiting A router which sends ICMP Source Quench messages MUST be able to limit the rate at which the messages can be generated.
If a packet is to be forwarded to a host on a network that is directly connected to the router (i.e., the router is the last-hop router) and the router has ascertained that there is n
The original set of rules can be found in RFC 950, and the new set of rules can be found in RFC1812.
Perhaps the most significant change on the near side of the 'net under RFC1812 is Classless Inter-Domain Routing (CIDR, pronounced "Cider").
Most of the other effects of RFC1812 and CIDR routing affect areas of the 'net closer to the backbone, and mostly work to reduce the size (or at least the rate of growth) of routing tables in backbone routers.

RFC 1812(Site not responding. Last check: 2007-10-07)
This document is an updated version of RFC 1716, the historical Router Requirements document.
RFC 791 [INTERNET:1] is the specification for the Internet Protocol.
One possible method of choosing the router-id that fulfills this requirement is to use the numerically smallest (or greatest) IP address (treating the address as a 32-bit integer) that is assigned to the router.

Although IP is an unreliable protocol that does not guarantee delivery, it is important to be able to inform a sender when delivery is not possible due to a semi-permanent, nontransient error.
However, RFC 792 contained some vagaries that were clarified in RFC 1122 (Host Network Requirements) and RFC1812 (Router Requirements).
RFC 792 states that ICMP must be used whenever IP itself needs to report a problem.
Since file-upload is a feature that will benefit many applications, this proposes an extension to HTML to allow information providers to express file upload requests uniformly, and a MIME compatible representation for file upload responses.
This RFC describes a mechanism to allow the DNS to carry location information about hosts, networks, and subnets.
This memo documents some experiences with the RFC 1797 [1] subnet A experiment (performed by the Net39 Test Group (see credits)) and provides a number of recommendations on future direction for both the Internet Registries and the Operations community.
Network service providers and corporate network operators are urged to ensure their networks are not susceptible to directed broadcast packets originating outside their networks.
