AS12935 — NOCOM Central node

AS12935 announces 2 IPv4 prefixes covering 9,216 addresses and 1 IPv6 prefixes.

About this network

An AS whose handle is a sentence fragment describing a network node.

What it's used for

• The network of a Swedish IT services and hosting provider. 9,216 addresses across two IPv4 prefixes, one IPv6 prefix, and two observed BGP neighbours.

Notable

• The inventory is 213.179.0.0/19 and 185.173.4.0/22, plus 2a02:6980::/32.
• The AS handle is NOCOM Central node.
• 185.173.4.0/22 carries the netname SE-BIZIT-20161014, naming a different company.
• The registry lookup for 213.179.0.0/19 failed, so nothing here describes that block's record.
• Six addresses were sampled and none returned a name.

Interesting

• Handles are meant to be short uppercase identifiers, and this one is a description with a space in it. Somebody filled the field with what the thing was rather than what to call it, and the answer stuck: every routing tool that displays this AS shows that phrase, which now describes a network node belonging to a company that no longer exists under that name.
• The one readable netname names a third company again. Between the handle, the AS name and the netname, three organisations appear in a record with two blocks in it, which is what serial acquisition looks like from outside.
• The 2016 date on that netname sits alongside a 185. prefix, consistent with space obtained late rather than inherited. Small providers that keep buying each other end up with a mix of old regional space and recent scraps, and the mix is legible in the address ranges alone.
• Nothing answers reverse lookups across either block.
