  DNS root zone - Wikipedia, the free encyclopedia
The term, when not otherwise qualified, is generally used to refer to the root zone of the largest global DNS system deployed on the Internet.
The combination of limits in the DNS and IP protocols means that there is a limit of thirteen root server names that can be accommodated within a root zone.
There are thirteen root server names that are authoritative for queries to the global DNS root zone, the maximum number possible.

 Interim signing of the root zone.
In the case of the root zone the particular importance of managing the transition with zero operational mistakes is a strong reason to separate the signing of the zone itself, with the associated key management issues, from the future management of signed delegations (of top level domains).
The assumption is that the operators of the root servers are trusted and that consistency of the zone among the root servers is a crucial property that MUST be preserved in emergencies.
The present, unsigned zone is published by the official slaves, the "root nameservers" transferring the zone securely from a hidden primary master and subsequently using the data to respond to queries.

 Root nameserver - Wikipedia, the free encyclopedia
A root nameserver is a DNS server that answers requests for the root namespace domain, and redirects requests for a particular top-level domain to that TLD's nameservers.
This final dot is implied, as modern DNS software does not actually require that the final dot be included when attempting to translate a domain name to an IP address.
There are quite a few alternative namespace systems with their own set of root nameservers that exist in opposition to the mainstream nameservers.

 glassey-dns-rzp-00.txt
The Intent of the Root Zone Protocol (RZP) is to allow for the dynamic mapping of DNS Root Zones at the DNS Server Level and it identifies most all the components that the new Syntax Model would affect as well.
The new DNS Nomenclature proposal is based around the addition of a ROOT ZONE TAG or RZT's as a zone identifier code, which is prepended like an Area Code, to the front of the existing FQDN.
ROOT ZONE FAILs can be addressed through policy in a number of manners, and as a default mode, we propose that the server attempts to recover a new copy of the ZONE TABLE from the master server or from the previous supplier of this ZONE TABLE, which was also cached locally in the Server.

Motivation for signing the DNS root In the special case of the root zone there are very strong reasons to take a slow and conservative approach to any changes with operational impact.
Motivation for signing the root zone now The reason DNSSEC is not yet widely deployable is that the problem of key management remains unsolved, especially where communication between the zone administrators for a parent zone and child zone is required.
Management and distribution of the zone file The present, unsigned zone is published by the official slaves, the "root nameservers", transferring the zone securely from a primary master and subsequently using the data to respond to queries.

 root zone
The influence of root zone temperature on photosynthetic acclimation to elevated carbon dioxide concentrations.
Active feeder roots are most dense around the drip line of a plant, so place soaker hoses to deliver to the root zone, not the neck of a large plant.
Adding a foot of soil to this root zone also is a bad move; it can suffocate with the same efficiency of having 24 people piled atop of you in a phone booth.

 Submission to the Workshop on Internet Governance 26
The management of the DNS root zone file, including the clerical task of preparing the root zone file for distribution to the root servers and the task of developing and applying policies to determine which new top-level domains will be allowed entry into the root zone.
Evaluation: The root zone file is a relatively small text file that lists the names of each top level domain as well as the IP addresses of the name servers for each of those domains.
Because DNS is an easy means for certain interests to exercise a great deal of worldwide control for a relatively tiny expense there will be great pressure for this Policy Organization to engage in policy making about things that go beyond how the DNS root zone should be managed.

DNS could also use heuristics, filters, and cross checks to accept data that is good and reject data that is bad.
If someone takes a moment to examine the DNS root file one of the first things that is seen is how small it is. And if you apply a bit of text compression the result is about 15K bytes - that's smaller than most of the cutesy little icons that decorate web pages.
We don't need DNS root servers at all - copies of the DNS root zone file could be easily disseminated by P2P networks, by IP multicast, and even be published in newspapers (in text or as a 2-D barcode).

 ICANN | Toward a Statement of the ICANN Mission
The DNS root zone file consists of a list of all top-level domains in the authoritative public DNS (currently 259 TLDs), along with the names and IP addresses of the primary and secondary name servers that are authoritative for each TLD.
Through its Root Server System Advisory Committee (RSSAC), which consists of the root name server operators and invited experts, ICANN is also responsible for developing and implementing policies relating to, for example, the distribution, location, and identity of the root name server operators.
For example, when planning and implementation testing are complete, ICANN will operate a dedicated primary root name server, a significant security enhancement that will eliminate the need of the root name servers to rely on one of the machines that handles public DNS queries to also provide the authoritative version of the root zone file.

 New.net: ISP Information
The root zone is nothing special as far as BIND is concerned.
But if you do have such a mechanism, then the method is to simply publish to root zone information gathered from our ftp location, and publish as you would for any other zone that you are authoritative for.
You can start and stop the dns service if you want to facilitate the transfer, but it is not necessary.

 How to configure DNS for Internet access in Windows 2000
DNS servers should not use dynamically assigned IP addresses because a dynamic change of address could cause clients to lose contact with the DNS server.
The name of the zone must be the same as the name of the Active Directory-based domain, or be a logical DNS container for that name.
A DNS server first queries its cache, then it checks its zone records, then it sends requests to forwarders, and finally it tries resolution by using root servers.

Traffic to the Internet root servers is heavy, but because host names are not usually resolved at this level, the load can be reasonably handled.
Instead, the root hints file provides referral information that can be useful during DNS name resolution to redirect a query to other servers that are authoritative for names located beneath the root.
For DNS servers operating privately on your internal network, the DNS console can learn and replace the contents of this file with internal root servers on your network, provided they are reachable through the network when you are setting up and configuring new DNS servers.

If you have a large distributed network and a complex DNS namespace, it is best to use an internal DNS root that is isolated from public networks.
Using an internal DNS root streamlines the administration of your DNS namespace by enabling you to administer your DNS infrastructure as if the entire namespace consists of the DNS data within your network.
The DNS server that hosts the private root zone in your namespace is considered to be authoritative for all of the names in the internal DNS namespace.

 heise online - .eu-Domain entered in the DNS root zone
After five years of preparations the domain.eu was entered almost surreptitiously on Friday night in the DNS root zone and hence activated within the Internet.
While at EUrid in Belgium they continue to wait to put the last signature under the agreement with the Internet Corporation for Assigned Names and Numbers (ICANN), the first "multinational country domain" was quickly entered after the US Department of Commerce gave the green light.
When the conditions of registration and the registrar contracts are published the equivocal role of.eu in the DNS will again be thrown into high relief: In point of fact.eu is a country domain (ccTLD), without, however being - strictly speaking - on the ISO´s list of country codes, from which ccTLD entries take their cue.

Methodology is to undertake a zone transfer and then analyze the delegations in the zone for errors and warnings.
What is 'correct' is unclear in the DNS specifications in some cases, so the checker does express an interpretation of the specifications.
The root zone (268 entries), 93 zones have at least 1 NS record that does not respond to a TCP query, 68 zones have >= 1 lame name server delegation, 35 zones have a MNAME that does not respond to mail, and various other smaller numbers of zones with other errors.

 IP: Proposed US Govt Status Quo Policy on DNS ROOT ZONE Control   (Site not responding. Last check: 2007-11-02)
This would mean that IPOC/CORE will be denied immediate insertion of their unilaterally determined "7 gTLDs" into the official IANA controlled ROOT ZONE.=A0 At least two of these 7 gTLDs are contested by other parties who have already mounted them in alternate ROOT servers.
In short, there is no crisis in terms of potential failure of the Internet, even if the DNS ROOT finds itself without any central authority over its "MASTER ROOT ZONE TABLE".=A0 Such central authority and control is actually not required.
I believe this recommendation embodies a sound non-zero-sum-game strategy, as compared to the warring parties tendency to see the DNS ROOT as a zero-sum game, wherein "what ever you gain must be taken from what I have".
