[arin-discuss] ARIN-discuss Digest, Vol 26, Issue 6

[Paul G. Timmins]

Sorry for the top post, I blame outlook.

What actually happened is that they had to look for any range of 1,000
numbers where they used less than 100 of them, and return anything they
couldn't justify. The relinquishment works by a coordinator (National
Pooling) that coordinates requests for new ranges, and uses LNP to port
the entire range of 1,000 numbers (minus numbers being used, if any
(these are known as "polluted" blocks because they aren't contiguous
ranges of 1,000)). (Local utilities commissions are involved in this
whole thing too, and getting numbers is a huge mess of paperwork)

Customers did not have to relinquish existing numbers (renumbering) and
the only energy required was that of the phone companies in basically
equal quantities (ILECs had to do this too, some of our number blocks
used to belong to the ILEC).

We don't really have an analog to LNP in the network. At the time, LNP
was an existing tool that could be leveraged for this, so it was that
much easier to do. The only issue was tracking down number inventory and
performing the accounting that should have been required under the NRUF
anyway (the telco equivalent to an ARIN justification).

Telcos and NPA/NXX assignments had a similar problem to solve.  CLECs
were
given entire exchanges (10,000 blocks of numbers) until NANPA realized
this
was not going to be sustainable with the number of new CLECs asking for
numbers.  They then cut assignments back to 1,000 blocks of numbers and
in
some cases asked CLECs to give back 9,000 phone numbers.  By then the
CLECs
had given out numbers throughout the entire 10,000 number range
(everyone
wants 1111 or 2222).  It caused some customer service issues and
definitely
a lot of time and energy to accomplish that relinquishment.

Returning IPs from these big blocks may be just as problematic ... a /22
here, a /24 there.  This could be a mess.
