AS12453 — KRAFTCOM-AS

AS12453 announces 9 IPv4 prefixes covering 6,400 addresses and 1 IPv6 prefixes.

About this network

An Austrian operator with 103 BGP neighbours and a founder still named in every record.

What it's used for

• Access and hosting. 6,400 addresses in nine IPv4 prefixes, one IPv6 /29, and 103 observed BGP neighbours.

Notable

• Every block shares the netname stem AT-KRAFTCOM3, with the allocation date appended on most of them. Those dates run from 20130719 to 20240930.
• The registrant on each is a person and a company together: Bernhard Kraft alongside KraftCom Service GmbH.
• Reverse DNS puts the address in reading order and appends a category: 2.56.161.0.dyn.kraftcom.at.
• First seen in routing data in May 2011.

Interesting

• The 3 in AT-KRAFTCOM3 has outlived whatever it was counting. Netnames one and two are not in this AS, but the third one became the template, so every allocation since — including one made in 2024 — carries a sequence number from a decade earlier.
• 103 neighbours against 6,400 addresses puts this network firmly on the interconnection side of the ledger. Nine /22-sized blocks acquired one at a time is a company buying address space as it needs it, while the peering is where the actual value sits.
