About this network

A small Estonian network announcing one IPv4 block and one IPv6 sub-allocation.

What it's used for

• 1,024 addresses in a single /22, one IPv6 /40, and two observed BGP neighbours.

Notable

• The IPv4 block is 45.132.64.0/22, out of 45.0.0.0/8 — space RIPE only began handing out after the regional pools were exhausted, and none of it existed in European routing tables before the 2010s.
• The AS itself was first seen in the routing data in February 2003.
• The IPv6 announcement is 2a0c:1180::/40, a sub-allocation rather than a provider's own /32.

Interesting

• The number is two decades older than the addresses it carries. AS numbers and address blocks are separate resources with separate lifetimes, and they part company routinely: the space an AS announced in 2003 can be long gone while the number itself changes hands, keeps its registration and picks up something new. Reading a routing table as though the two aged together is one of the easier mistakes to make.
• The holder shares its name with Xvid, the open-source MPEG-4 video codec that came out of the fallout when DivX went commercial. The registry says nothing about the connection, and a name is not evidence of one.
