Summary

Alterra Technologies Poland

Russian Federation · AI-generated

hosting business nsp

The AS handle NUVIRA-AS is held by Alterra Technologies Poland.

What it's used for

  • The address space carries hosting infrastructure, evidenced by the netname ALTERRA-HOST-PL and reverse DNS entries pointing to alterra.host.
  • The network announces 256 IPv4 addresses and 3 IPv6 prefixes, with only 2 observed neighbours, indicating a small-scale hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web and API endpoints for Alterra's hosting services, as the company operates as a Network Service Provider (NSP) in Europe.

Notable

  • The RDAP registrant for the announced prefix 81.90.20.0/24 is listed as Admin; Alterra Technologies Poland, which aligns with the AS holder identity.
  • The address inventory is compact, consisting of a single /24 IPv4 block and three IPv6 prefixes, consistent with a focused hosting operation.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-02, 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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
