Summary

Bulsat Ltd.

Bulgaria · AI-generated

isp residential bulgaria cable

The AS handle BULSATTV-AS is held by Bulsat Ltd.

What it's used for

  • The address space carries residential broadband traffic, evidenced by the reverse DNS record 87-121-130-254.bulsattv.com and the netname NETERRA-BULSATTV-NET.
  • The network announces 1024 IPv4 addresses within a single prefix (87.121.128.0/22) and maintains only 1 observed neighbour, a ratio indicative of a local access provider rather than a transit carrier.
  • Traffic from this AS consists of subscriber eyeballs for the Bulsat cable television and internet service provider operating in Bulgaria.

Notable

  • The RDAP registrant for the announced prefix is listed as Neterra contacts, which aligns with the netname NETERRA-BULSATTV-NET and the announcer Bulsat Ltd.
  • The address inventory is compact, consisting of a single contiguous /22 block with no IPv6 prefixes in inventory.

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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
