isp residential ukraine access

MEREZHA-UA-AS is operated by PP "Merezha".

What it's used for

  • The address space carries residential and business internet access, evidenced by netnames MEREZHA-NET and UA-ALFA associated with registrants PP "Merezha" and PRIVATE ENTERPRISE "ALFA NETWORK".
  • The AS announces 38400 IPv4 addresses across 6 prefixes and maintains a single observed neighbour, a ratio indicative of an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber internet access for end-users in Ukraine, consistent with the operator's role as a regional internet service provider.

Notable

  • The address inventory is composed of mixed /17, /21, /22, and /23 blocks, all located in Ukraine.

Reputation

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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
