isp residential ukraine

AS-SKYNET-UA is operated by FOP Lizanchuk Yaroslav M., a Ukrainian sole proprietorship.

What it's used for

  • The address space carries residential and small business traffic, evidenced by reverse DNS entries like 212-79-126-64.skynet.net.ua and netnames SKYNET-UA-NET and SKYNET.
  • The AS announces 1,280 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 24 observed neighbours; this ratio indicates an access network providing last-mile connectivity rather than transit.
  • Traffic from this AS consists of subscriber eyeballs and local web/API endpoints for customers in Ukraine.

Notable

  • Registrants align with the announcer, with FOP Lizanchuk Yaroslav M. listed for the primary block and Abuse-C Role for the secondary block.
  • The address inventory is compact, consisting of one /22 and one /24 in IPv4, plus a single /48 in IPv6.

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 1,782 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.
