Summary

AlterTEL

Poland · AI-generated

telecom business poland

ALTERTEL-AS is operated by AlterTEL Sp. z o.o.

What it's used for

  • The address space carries corporate and telecommunications infrastructure, evidenced by the netname ALTERTEL-NET and registrants AlterTEL NOC and AlterTEL Sp. z o.o.
  • The AS announces 1280 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small-scale business or internal corporate estate rather than a large access network
  • Traffic consists of internal corporate communications and telecommunications equipment management for the Warsaw-based operator

Notable

  • Registrants AlterTEL NOC and AlterTEL Sp. z o.o. align directly with the AS holder, confirming consistent ownership
  • The address inventory is compact, comprising a single /22 block and a single /24 block, both within the 109.95.136.0/22 range

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 1,778 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.
