isp residential ukraine

MASTERLINK-NET is operated by ISP RIAD Ltd.

What it's used for

  • The address space carries residential and business internet access, as indicated by the netname RIAD-NET and the registrant ISP RIAD Ltd.
  • The network announces 1792 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio characteristic of an access network providing last-mile connectivity rather than transit.
  • Traffic from this AS consists of subscriber eyeballs and local business endpoints within the Rostov region of Ukraine.

Notable

  • All registrants for the announced prefixes are ISP RIAD Ltd, which agrees with the AS holder MASTERLINK-NET ISP RIAD Ltd.
  • The address inventory is compact, consisting of three contiguous or near-contiguous blocks in the 91.223.0.0/16 range.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
