Summary

Delta Telesystems

Russia · AI-generated

isp telecom business

Ten prefixes, six netnames, and four blocks whose only registered party is an abuse address.

What it's used for

  • A Russian regional access network. 5,632 addresses across ten IPv4 prefixes, one IPv6 prefix 2001:678:68c::/48, and thirteen observed BGP neighbours.

Notable

  • Netnames include DELTA-TELESYSTEMS-NET, RU-DELTA-TELESYSTEMS-20220104, RU-SIBTEL-20040226, SIBTEL, SIBTEL-NETWORK, PALCOMNET and TECHNO-NET.
  • Four /24s list Abuse-C Role as their sole registrant, with no organisation named at all.
  • One /21 is registered to a named individual rather than a company.
  • Sampled names split into .dynamic. and .static. branches, as in 188-0-42-0.dynamic.deltatelesystems.ru and 91-206-16-128.static.deltatelesystems.ru.

Interesting

  • Six netnames across ten blocks, four of them naming companies that are not the holder, is an acquisition trail written into the registry. Each label is a fossil of whoever received that block, and the current operator inherited all of them rather than renaming anything.
  • The blocks whose only contact is an abuse role have degraded as far as a record can go while remaining valid. The one thing left is where to send complaints, which is the one thing the registry actually enforces.
  • Separating dynamic and static addresses in the DNS names tells anyone reading a log which kind of address they are looking at, without asking the operator. Networks elsewhere in this range publish no such distinction.

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: 453 networks and 1,853 prefixes, as published 2026-11-05. 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.
