Ukraine · AI-generated

isp residential ukraine rnc

RNC-AS is operated by RNC Ltd., a Ukrainian internet service provider.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as host-254-158.rnc.com.ua and host-255-101.rnc.com.ua.
  • The AS announces 2048 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio indicative of an access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and local business endpoints within Ukraine, consistent with RNC Ltd.'s role as a regional ISP.

Notable

  • Registrants for the two announced prefixes differ: 91.196.156.0/22 is registered to RNC Ltd., while 217.66.100.0/22 is registered to Emplot Ltd., suggesting a historical acquisition or lease arrangement.
  • The address inventory is compact, consisting of two /22 blocks, with one prefix showing reverse DNS for a2group.emplot.net, further linking the space to the Emplot entity.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
