Summary

Ultracom Ltd.

Bulgaria · AI-generated

business bg corporate

The AS handle ULTRACOM-AS is held by Ultracom Ltd.

What it's used for

  • The address space carries corporate and leased infrastructure, evidenced by netnames BG-MTELNET-20051125, BG-MTELNET-20080418, ULTRACOM-BG, and NETERRA-ULTRACOM-NET.
  • With 5,888 IPv4 addresses announced across 7 prefixes and only 2 observed neighbours, the ratio indicates an internal corporate estate or small business network rather than a transit or large-scale access provider.
  • Reverse DNS entries for the 31.13.198.0/24 block point to neterra.net, indicating this specific segment is associated with Neterra, a Bulgarian IT services company.

Notable

  • Registrants for the majority of prefixes are listed as A1 Bulgaria EAD Registry and A1 Bulgaria EAD Abuse, while the 31.13.198.0/24 prefix is registered to Neterra contacts.
  • The address inventory is a mix of larger /21 blocks and smaller /23 and /24 blocks, with the largest allocations associated with the BG-MTELNET netnames.

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 1,782 prefixes, as published 2026-10-16. 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.
