eDNS and ARIN

[Jim Fleming]

For people not familiar with all of the internal
workings of the Domain Name System (DNS).
There is a very important place where eDNS
and ARIN overlap.

That overlap comes in the management of
the .ARPA Top Level Domain (TLD). To be more
specific, I should say the "psuedo" TLD....

	IN-ADDR.ARPA

The following section of the IPv4 address space
can be used to illustrate.

======================================================
...
MA	8.0.0.0	Bolt Beranek and Newman Inc. (NET-BBN-NET-TEMP)
NY	9.0.0.0	IBM Corporation (NET-IBM)
CA	10.0.0.0	IANA (RESERVED-6)
CA	11.0.0.0	DoD Intel Information Systems (NET-DODIIS)
FL	12.0.0.0	AT&T ITS (NET-ATT)
CA	13.0.0.0	Xerox Palo Alto Research Center (NET-XEROX-NET)
CA	14.0.0.0	Public Data Network (NET-PDN)
CA	15.0.0.0	Hewlett-Packard Company (NET-HP-INTERNET)
CA	16.0.0.0	Digital Equipment Corporation (NET-DEC-INTERNET)
CA	17.0.0.0	Apple Computer, Inc. (NET-APPLE-WWNET)
MA	18.0.0.0	Massachusetts Institute of Technology (NET-MIT-TEMP)
...
======================================================

In the Domain Name System, in order for Hewlett-Packard to
operate effectively, they need to be delegated the following zone...

	15.IN-ADDR.ARPA

>From a registry point of view, this is not much different from
delegating a company a name like 15-in-addr.com. While
it is true that most companies would not want such a name
for marketing purposes, it is very important for the companies
and organizations above to be properly register in the IN-ADDR.ARPA
psuedo Top Level Domain.

There is an item on the agenda for the upcoming eDNS meeting
in Atlanta to discuss ARIN and other issues regarding IN-ADDR.ARPA.
The Root Name Server owner/operators have to make sure that
the delegations made in IN-ADDR.ARPA are handled properly to
maintain a stable Internet.

A stable Internet requires stable Domain Name and IP management.
That management comes via stable, well-managed registries.
