Summary
KraftCom Service
isp hosting
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 from20130719to20240930. - The registrant on each is a person and a company together:
Bernhard Kraftalongside 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
3inAT-KRAFTCOM3has 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.

Reputation
Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
