AS13671 — VRIS-AS-BLOCK

AS13671 announces 1 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.

About this network

A single block whose netname records the year, the product and the sequence number of an allocation made for dial-up.

What it's used for

• A carrier-held AS. 512 addresses in the single IPv4 prefix 68.128.232.0/23, one observed BGP neighbour, and no IPv6 announced.

Notable

• The block is netname NETBLK-UUNET97DU-3BLK, registered to the carrier with an abuse contact.
• The netname stacks four things: the words for network block, a former carrier's name, a two-digit year with a product abbreviation, and a counter with the words for block again.
• The AS handle is VRIS-AS-BLOCK, shared with other AS numbers rather than naming this one.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Two-digit years in identifiers are a habit that predates the anxiety about them and survived it. This one dates the allocation to a period when the abbreviation for dial-up was worth putting in the field, because there was more than one kind of access to distinguish.
• The word for network block appears twice in one netname, once at the front and once at the end, so the field says what it is, whose it is, when it was cut, and that it is a block, twice.
• Space cut for modems, in the year the netname records, is still announced, still routed, and now carries whatever the carrier moved onto it.
