Summary

Vivacom

Bulgaria · AI-generated

telecom residential business bg

TELNET-AS is operated by Vivacom Bulgaria EAD, the largest telecommunications provider in Bulgaria.

What it's used for

  • The address space carries customer and corporate endpoints, evidenced by reverse DNS entries like 15876.telnet.bg and netnames such as TELNET-STUDENTS and TELNET-CORP.
  • With 1792 IPv4 addresses announced across 6 prefixes and only 1 observed neighbour, the network functions as an access provider rather than a transit hub.

Notable

  • Registrants for the largest prefixes are listed as BTC IP ADDRESS SPACE administration; Vivacom Bulgaria EAD, reflecting the historical merger of BTC (Bulgarian Telecommunications Company) and Vivacom.
  • Vivacom was formed through the merger of the former state-owned fixed-line operator BTC and the mobile operator Vivacom, consolidating Bulgaria's primary telecom infrastructure.
  • The inventory consists of six IPv4 prefixes with no IPv6 announcements, including a /23 block and five /24 blocks.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
