residential isp sumy ukraine

CHEREDA-SM-AS is operated by Chereda, a regional internet service provider based in Sumy, Ukraine.

What it's used for

  • The address space carries residential access traffic, evidenced by reverse DNS entries such as i0.access-89-19-122.joule.sm.chereda.net and i254.access-89-19-125.panda.sm.chereda.net.
  • The AS announces 3072 IPv4 addresses across 2 prefixes and maintains 1 observed neighbour, a ratio indicative of an access network rather than a transit provider.

Notable

  • Registrants for both announced prefixes (UA-TELECOMS-SM-PARTITION and CHEREDA-SM-NET) consistently list Grygoriy Chereda and associated NOC entities, aligning with the AS holder.
  • The inventory consists of two distinct IPv4 blocks: 89.19.120.0/21 and 193.110.16.0/22, with no IPv6 prefixes announced.

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 1,783 prefixes, as published 2026-10-17. 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.
