Summary

Retel JSC

Bulgaria · AI-generated

isp residential bulgaria fiber

BG-RETEL-AS is operated by Retel JSC.

What it's used for

  • The address space carries residential and business internet access, evidenced by netnames such as BG-RETEL and NETERRA-RETEL-NET associated with Retel JSC and Neterra contacts.
  • The AS announces 5376 IPv4 addresses across 5 prefixes and 2 IPv6 prefixes, with 4 observed routing neighbours. This ratio of address space to peering partners indicates an access network providing connectivity to end-users rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and business users accessing the internet via Retel's fiber and fixed-line infrastructure in Bulgaria.

Notable

  • Registrants for the announced prefixes are consistent with the announcer, listing Retel JSC and Neterra contacts for all five IPv4 blocks.
  • The address inventory includes a mix of blocks registered under different netnames, including BG-NETERRAIP-20080305 and NETERRA-RETEL-NET, reflecting historical acquisitions or rebranding within the Neterra/Retel corporate structure.

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.
