Summary

Asyst EOOD

Bulgaria · AI-generated

business bg ipv4

ASYST-AS is operated by Asyst EOOD.

What it's used for

  • The address space carries business traffic, evidenced by netnames Asyst-Net and Asyst associated with registrants Asyst EOOD and Evolink.
  • The AS announces 1536 IPv4 addresses across 3 prefixes and maintains 4 observed neighbours, a ratio consistent with a small-scale business or internal corporate network rather than a transit provider.
  • Traffic from this AS represents office workers or internal corporate endpoints for Asyst EOOD, a Bulgarian entity.

Notable

  • Registrants for the two largest prefixes (91.236.144.0/22 and 77.76.12.0/24) are Asyst EOOD, matching the AS holder.
  • The prefix 82.119.87.0/24 lists Evolink as the administrative and technical contact, indicating a distinct ownership or management relationship for this specific block.
  • The inventory consists of three IPv4 prefixes with no IPv6 announcements.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, 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: 442 networks and 1,783 prefixes, as published 2026-10-20. 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.
