Summary

Sixty K

Bulgaria · AI-generated

business bg ipv4

The AS handle AS60K is held by Sixty K Ltd.

What it's used for

  • The address space carries business traffic, evidenced by reverse DNS entries pointing to ip.btc-net.bg and netnames BG-BTC-20091002 and NET60K.
  • The network announces 512 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small-scale business or internal corporate estate rather than a large access or transit provider.
  • Traffic from this AS consists of business endpoints and internal services associated with the operator's operations in Bulgaria.

Notable

  • Registrants for the announced prefixes are BTC IP ADDRESS SPACE administration and Vivacom Bulgaria EAD, which align with the announcer's identity as a Bulgarian entity managing IP space.
  • The address inventory consists of two /24 blocks, one associated with Vivacom and one with the netname NET60K, reflecting a compact and specific allocation.

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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
