Summary

OOO Integral telesystems

Russian Federation · AI-generated

business russia small

The AS handle INTSYS-AS is held by OOO Integral telesystems.

What it's used for

  • The address space carries a single IPv4 prefix, 185.58.205.0/24, with the netname autosoft-ru-1 and registrant OOO Integral telesystems.
  • The network announces 256 IPv4 addresses across 1 prefix and maintains 2 observed neighbours, indicating a small-scale access or internal corporate estate rather than a transit provider.
  • Traffic from this AS consists of internal corporate endpoints and services associated with the operator's business operations in the Russian Federation.

Notable

  • The RDAP registrant OOO Integral telesystems matches the registry holder and the AS handle INTSYS-AS.
  • The address inventory is minimal, consisting of a single /24 block with no IPv6 prefixes in the inventory.

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 1,781 prefixes, as published 2026-10-16. 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.
