Summary

Merezha

Netherlands · AI-generated

business ukraine netherlands

The AS handle LIR-UKRAINE-AS is held by Merezha LTD.

What it's used for

  • The address space carries business and ISP services, evidenced by netnames UK-MEREZHA, UK-MEREZHA-20201015, and ispwifi.
  • The AS announces 1792 IPv4 addresses across 4 prefixes with only 1 observed neighbour, a ratio that indicates an access or business network rather than a transit provider.

Notable

  • Registrants for the largest prefixes are NOC; Merezha LTD and noc; ispwifi-net, which align with the announcer's identity.
  • The address inventory is concentrated in the Netherlands, with all 4 announced prefixes located there, despite the handle referencing Ukraine.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

On Spamhaus ASN-DROP Spamhaus lists this entire network (associated domain bignet.ua) as controlled by, or hijacked for, cybercrime. Many operators null-route everything it originates.

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 1,781 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.
