About this network

A registered association with 512 addresses and eighteen BGP neighbours.

What it's used for

• The network of a German non-profit association based in Würzburg. 512 addresses in one IPv4 prefix, one IPv6 prefix, and eighteen observed BGP neighbours.

Notable

• The inventory is 194.145.150.0/23, netname GEFOEKOM-NET, registered to GeFoekoM e.V.
• IPv6 is 2001:1578:200::/40.
• The AS handle is GEFOEKOM Wuerzburg, Germany.
• First observed in the routing archive at the earliest date the archive holds.
• Three addresses were sampled and none returned a name.

Interesting

• e.V. marks an eingetragener Verein, a registered association under German law. It is the legal form clubs, societies and community projects take, and it appears in the routing table more often than one might expect: the internet's early German build-out ran substantially through associations rather than companies.
• Eighteen neighbours on 512 addresses inverts the usual ratio. A network with almost no address space and a great deal of interconnection is not serving subscribers; it is somewhere other networks meet, or it is run by people who peer because peering is the interesting part.
• The /40 in IPv6 is 65,536 times the address space of the /23 in IPv4, and it is a small IPv6 allocation. The two protocols are not measured on the same scale, and comparing prefix lengths across them is a reliable way to be wrong about a network's size.
