Summary

Ukraine · AI-generated

isp residential ukraine small

The AS handle FOURSEASONSISP-AS is held by GREEN ROAD LLC.

What it's used for

  • The address space carries residential or small business traffic, indicated by the netname UNDERNET-NET2 and reverse DNS entries like s-79-110-137-64.under.net.ua.
  • The network announces 256 IPv4 addresses across 1 prefix with 1 observed neighbour, a ratio typical of a small access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber internet access provided by UnderNet, a Ukrainian internet service provider.

Notable

  • The RDAP registrant for the announced prefix is UnderNet LLC, which differs from the AS holder GREEN ROAD LLC, suggesting a corporate restructuring or lease arrangement.
  • The inventory consists of a single /24 block, representing a compact and focused address allocation.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
