Summary

JSC Avantel

Russian Federation · AI-generated

isp telecom business

Four company names in one small record, and none of them is the same company.

What it's used for

  • A regional operator's network. One IPv4 /24 announced from the Russian Federation, no IPv6, two hundred and fifty-six addresses, across three observed BGP neighbours.

Notable

  • The AS handle is one word naming a business. The registered holder is a different company under a joint-stock legal form.
  • The single block's netname is a country code, a third company's brand and a date, and its technical contact is a network operations role belonging to a fourth.
  • That date is from the middle of the nineteen-nineties, which makes it among the oldest allocation dates seen anywhere in this stretch of numbers.
  • Two hundred and fifty-six addresses are announced as one route, the smallest that can be.
  • Three addresses were queried for reverse DNS and none returned a name.

Interesting

  • Four names across four fields is a block that has been sold, merged or absorbed several times, with each field updated by whoever needed it and left alone by everyone else. The netname is the oldest layer, the holder the newest, and the handle sits somewhere in between.
  • A nineteen-nineties allocation on a number issued years later means the block and the number came together long after either was created. Small records with old dates are usually address space that outlived the business it was issued to.

Reputation

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 1,779 prefixes, as published 2026-10-21. 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.
