Hi Paul,

You've conflated a few things here.

ARIN manages the registry of IP addresses used in North America
(approximately). The primary purpose of the registry is to deconflict
the use of addresses in multi-organizational networks such as the

ARIN does not control Internet routing. There is no central authority
for Internet routing. However, ISPs typically rely on ARIN to tell
them who controls a block of IP addresses before they'll accept a
customer's request to route it. It's a self-enforcing system - ISPs
that don't do so can be cut off by their ISPs.

ARIN does not control any "root servers." That has to do with the DNS
system which operates under ICANN. ARIN's relationship with the DNS is
only tangential - it partially controls a couple of subdomains which
are used for "reverse DNS," finding names starting from the IP
addresses. The DNS is also unrelated to Internet Routing.

Apropos of nothing, I have what I bill as "Al Gore's Router." It's the
Cisco Pro 2501 router used to connect Gore's 2000 DC campaign office
to the DNC and subsequently the Internet.
