AS14103 — ACDNET-ASN1

AS14103 announces 9 IPv4 prefixes covering 52,736 addresses and 1 IPv6 prefixes.

About this network

Every netname is numbered and carries a protocol version, on a network that also announces IPv6.

What it's used for

• A regional ISP. 52,736 addresses across 61 IPv4 prefixes plus one IPv6 prefix, 2607:fd80::/32, with 22 observed BGP neighbours.

Notable

• The netnames run ACDNET-V4-2 through ACDNET-V4-8, all registered to ACD.net.
• One block, 38.46.88.0/21, carries COGENT-A, a transit provider's generic label.
• Three of eighteen sampled addresses returned a name, in two forms: 38-46-93-254-static.acd.net and 69-63-227-255.static.acd.net.

Interesting

• Numbering netnames by protocol version implies a matching set for the other one. There is a single IPv6 prefix here and it needs no numbering, so the scheme anticipated a symmetry that the address space never developed.
• The two reverse forms differ only in a dot. One glues static onto the label with a dash; the other makes it a subdomain. Once both exist, a name has to be parsed rather than pattern-matched, and that difference survives because nothing forces a zone to be consistent.
• A transit provider's generic netname on one block means that block was assigned rather than allocated. The ISP announces it, but the registry credits the provider.
• Twenty-two neighbours against 61 prefixes is a network that peers locally as much as it buys transit, which is the economics of a regional operator sitting near an exchange.
