Summary

Sumy Online

Ukraine · AI-generated

isp residential ukraine regional

The AS handle SINSOFT-AS is held by Sumy Online Ltd.

What it's used for

  • The address space carries residential access traffic, evidenced by the reverse DNS record 254-242-pptp.online.sumy.ua which indicates PPTP-based connectivity for end-users.
  • The network announces a single IPv4 prefix, 193.111.240.0/22, comprising 1024 addresses, with no IPv6 prefixes in inventory.
  • With only one observed neighbour in the routing system, the low neighbour count relative to the address block suggests a local access or eyeball network rather than a transit provider.

Notable

  • The RDAP registrant Sumy Online Ltd matches the registry holder name, confirming consistent ownership of the sinsoft-net netname.
  • The inventory consists of a single contiguous /22 block, representing a compact and focused address estate for a regional operator.

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 1,846 prefixes, as published 2026-11-11. 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.
