Network type: residential

AS15108 announces 33 IPv4 prefixes covering 317,440 addresses and 1 IPv6 prefixes.

About this network

Three date formats in the netnames, one of them a season.

What it's used for

• A fibre provider's network. Thirty-nine IPv4 prefixes and one large IPv6 allocation announced from the United States, over three hundred thousand addresses, with thirty-four observed BGP neighbours.

Notable

• The netnames date themselves three incompatible ways: ALLO-2020AUG05-140-228-128-0 spells the month, ALLO-20200825-01 runs the digits together with a counter, and ALLO-SUMMER-2026 gives a season and a year.
• Other blocks use ACL-99, an initialism with a counter, and ALLO-NETBLK-72-8-64-0, the address written into the name.
• Eight of eighteen sampled addresses answered, in a five-label form such as 72-8-111-254.hst01-oa01.hst.ne.allofiber.net: the address, a device and port code, a site code, a two-letter state and the domain.
• One answering address puts a different two-letter state in that position, so the reverse names place one site outside the rest of the footprint.
• One registry lookup failed, so that block's ownership is unknown rather than absent.

Interesting

• The three date conventions are the find. All three come from the same holder and encode the same kind of fact, so a tool sorting this operator's blocks by the dates in their names has to parse a spelled month, a compact number and a season, and the season has no day at all.
• Naming the site and state in reverse DNS maps the network's footprint for anyone who reads it.
