AS12759 SOCO-AS Nordstrasse 102

A sole trader with 25,600 addresses, 128 BGP neighbours, and a street address in the AS handle.

What it's used for

• A German access and hosting provider. 25,600 addresses across four IPv4 prefixes, one IPv6 prefix, and 128 observed BGP neighbours.

Notable

• Three /19s — 78.153.64.0, 188.126.160.0, 212.16.224.0 — plus one /22.
• The registry holder reads Stephan Fuss trading as SoftCom Datensysteme.
• The AS handle is SOCO-AS Nordstrasse 102.
• Dated netnames run DE-SOCO-20070629, DE-SOCO-20090723 and DE-SOCO-20151127.
• The RDAP lookup for 212.16.224.0/19 failed, so its registration was not retrieved.
• Reverse names carry the address backwards: 78.153.72.0 answers as 0-72-153-78.dynamic-ip.soco.net, and the suffixes split into dynamic-ip.soco.net, static-ip.soco.net and soco-dsl.de.

Interesting

• Nordstrasse 102 is a postal address that ended up in the AS handle field. Somebody filled in a form with the street line where the name went, and it has been the network's public label ever since, because changing an AS name means touching records other operators have already written into their filters.
• 128 neighbours is a serious peering footprint, and it sits under a registration that names an individual person trading under a business name rather than a company. The registry records legal form, not scale.
• The reverse names run the octets in the order in-addr.arpa uses rather than the order the address is written in, which is the giveaway that the zone file was generated from the delegation itself rather than from a list of addresses.
