Summary

Memset

United Kingdom · AI-generated

hosting cloud dedicated uk

MEMSET is operated by Memset Ltd.

What it's used for

  • The address space carries hosting infrastructure, evidenced by netnames such as UK-MEMSET-19991216 and registrants including IOMART NOC and MEMSET Ltd.
  • The AS announces 21,504 IPv4 addresses across 8 prefixes and 1 IPv6 prefix, with a single observed neighbour, indicating a hosting or content delivery role rather than transit.
  • Traffic from this AS consists of dedicated servers, cloud VPS, and IaaS endpoints serving Memset's UK-based cloud hosting customers.

Notable

  • Registrants consistently list IOMART NOC, MEMSET Ltd, and IOMART ABUSE across all prefixes, reflecting the historical relationship between Memset and its parent company IOMART.
  • Memset was acquired by IOMART, which explains the persistent IOMART references in the RDAP registrant data alongside the Memset brand.
  • The inventory includes a large /19 block (213.170.0.0/19) alongside several /21 and /22 blocks, all located in the United Kingdom.

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

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 445 networks and 1,817 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.
