AS12998 — BGNET-AS

AS12998 announces 4 IPv4 prefixes covering 3,584 addresses and 1 IPv6 prefixes.

About this network

Three reverse-name formats and four netname styles, all on one small provider's four blocks.

What it's used for

• A Ukrainian internet provider. 3,584 addresses across four IPv4 prefixes, one IPv6 prefix, and 15 observed BGP neighbours.

Notable

• The netnames are UA-BGNET-20190411, UA-BGNET, UNLIMTELECOM-NET and AKCECC-PI1, all registered to the same holder.
• Ten of twelve sampled addresses returned names in three forms: 5.183.201.0.bg.net.ua, net-101-0-3.bg.net.ua and static-91-196-101-255.bg.net.ua.

Interesting

• Four blocks and four different netname conventions: one dated, one bare, one naming an absorbed company, and one an opaque code ending in PI1. Every acquisition and every registration era left its own style, and because netnames are never revised the record accumulates them all.
• PI1 marks provider-independent space, address space that belongs to the holder rather than to an upstream and can be carried between providers. Marking that in the netname is genuinely useful and almost nobody does it, since the distinction is otherwise invisible without checking the registry directly.
• The reverse names come in three formats on four blocks. One writes the address forwards with the domain appended, one uses a net- prefix with a partial address, and one marks static assignments explicitly. Each block was configured by whoever ran it at the time, and nothing has ever forced them into agreement.
• Fifteen neighbours for 3,584 addresses. Small Ukrainian providers peer heavily at national exchanges, which is how a network this size reaches the rest of the country directly.
