AS16740 — -Reserved AS-

AS16740 announces 16 IPv4 prefixes covering 8,704 addresses and 15 IPv6 prefixes.

About this network

The handle is a registry placeholder, and the reverse names claim a dozen other providers.

What it's used for

• A provider's network. Eighteen IPv4 prefixes and seventeen sixth-version prefixes announced from the United States, seven thousand six hundred and eighty addresses, through sixty-six observed BGP neighbours.

Notable

• The AS handle is not a name. It is the registry's placeholder text for a number held in reserve, dashes included, sitting on an autonomous system that announces thirty-five prefixes.
• Netnames name upstreams rather than purposes: two carriers appear by brand, one block is marked as portable space, one as a data centre with a four-digit number, and one is named for support of both protocol versions at once.
• One block's registrant is a different company followed by a role account.
• Fifteen of eighteen queried addresses answered, and the names belong to consumer providers on three continents: cable, telephone and mobile brands, and one large hardware maker's corporate domain.
• Every one of those names embeds the address it answers for.

Interesting

• Reverse names are set by whoever controls the zone for the addresses, so names shaped like a dozen unrelated providers on one holder's space means the zone is being generated to imitate them rather than to describe anything here.
• A reserved-text handle beside sixty-six neighbours is the sharpest contrast in the record: the registry believes this number is unused, and the routing table shows it very much in use.
