Summary
Zagalni Merezhi
business ukraine ipv4
IU-AS is the AS handle for Zagalni Merezhi Ltd, a Ukrainian network operator.
What it's used for
- The address space carries general network traffic, indicated by the netname
GENERAL-NETWORKSacross all prefixes. - The single reverse DNS record
fmi-254.ipm.lviv.uasuggests connectivity to or service for the Lviv region, specifically referencing an IPM (Internet Provider of Ukraine) domain. - With 3072 IPv4 addresses announced across 3 prefixes and 10 observed neighbours, the ratio indicates a mid-sized access or regional business network rather than a large transit provider.
Notable
- All three announced prefixes share the same registrant, Company "Zagalni Merezhi" Ltd, and the netname
GENERAL-NETWORKS, showing consistent ownership and naming. - The inventory consists of three /22 blocks, all located in Ukraine, with no IPv6 prefixes announced.
- The AS has been visible in routing tables since 2003, indicating a long-standing presence in the Ukrainian internet infrastructure.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
