Unclassified RIPE
Summary
Evolink
isp residential bulgaria access
The AS handle HEROS-AS is held by Evolink EAD.
What it's used for
- The address space carries residential subscriber traffic, evidenced by reverse DNS entries such as
pc64.centrum-group.comand the netnameBG-EVOLINK-961022. - The AS announces 512 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.
- Traffic from this AS consists of consumer internet access for residential customers in Bulgaria.
Notable
- The registrants for both announced prefixes are listed as Evolink EAD, which aligns with the operational identity of the network despite the AS handle referencing Heros Communication Holding Ltd.
- The address inventory is compact, consisting of two contiguous /24 blocks within the 194.12.0.0/16 range.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 446 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.
