Summary

A1

Belarus · AI-generated

residential isp belarus a1

ASTELGAROR is operated by A1, the major telecommunications provider in Belarus.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries pointing to skifnet.by and netnames such as A1-BELARUS.
  • The AS announces 1536 IPv4 addresses across 4 prefixes with only 1 observed neighbour, a ratio characteristic of an access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and end-user internet access for A1's customer base in Belarus.

Notable

  • Registrants for three of the four prefixes are listed as "Unitary enterprise A1; Velcom RIPE Admins" with netname A1-BELARUS, while the fourth prefix (217.21.38.0/23) is registered to "Netland ODO" with netname BY-INTERNETSERVICE-20000926.
  • The address inventory is small and fragmented, consisting of two /23 blocks and two /24 blocks, all located in Belarus.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, 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.
