Summary

business it-services sofia

AS-ZEROBYTE is held by Zero Byte Ltd.

What it's used for

  • The space carries IT services infrastructure, indicated by the netname ZeroByte-Net and registrants Evolink and Lirex Net.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix against 34 observed neighbours, a ratio consistent with a transit or peering-heavy role rather than a large access network.
  • Traffic from this AS consists of web development, cloud solutions, and IT services endpoints for clients in Sofia, Bulgaria.

Notable

  • Registrants Evolink and Lirex Net differ from the AS holder Zero Byte Ltd, suggesting leased space or post-acquisition history.
  • The address inventory is small, consisting of a single /24 block and a /32 IPv6 prefix.

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.
