AS16766 — -Reserved AS-

AS16766 announces 7 IPv4 prefixes covering 9,984 addresses and 7 IPv6 prefixes.

About this network

The registry calls this number reserved, and it announces more sixth-version prefixes than fourth.

What it's used for

• A provider's network. Seven IPv4 prefixes and ten sixth-version prefixes announced from the United States, nine thousand nine hundred and eighty-four addresses, through three observed BGP neighbours.

Notable

• The AS handle is the registry's placeholder text for a number held in reserve, dashes included, rather than any name.
• The holder line does give a name, the company's three words hyphenated in capitals.
• All seven blocks are registered to that company under one netname: two letters and a three-digit number, with no word for a network and no counter.
• Those two letters are the company's initials and also the usual abbreviation for a technology department, so the label reads two ways.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• The reserved placeholder is not unique to this holder. It is what a registry writes when the number's own record was never filled in, and it survives because nothing in routing reads that field.
• More sixth-version prefixes than fourth is unusual and points at a provider that got its newer space in one grant and has been splitting it for customers, while the older space was accumulated a piece at a time.
• One netname across two unrelated parent ranges means the company files by owner rather than by purpose, so the registry cannot tell you what any of it is for.
