Summary

Gladserv

United Kingdom · AI-generated

hosting business uk

GLADSERV is operated by Gladserv Limited.

What it's used for

  • The address space carries hosting infrastructure, evidenced by the netname UK-GLADSERV-20151127 and reverse DNS entries pointing to gladserv.net.
  • The AS announces 1024 IPv4 addresses and 2 IPv6 prefixes, with only 1 observed neighbour in RIS, indicating a small-scale hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web servers, virtual machines, and email services for developers and businesses, consistent with Gladserv's provision of scalable hosting and virtual servers.

Notable

  • The registrant Gladserv Limited matches the AS holder, confirming direct ownership of the announced space.
  • The inventory consists of a single IPv4 block (185.128.208.0/22) and two IPv6 prefixes, representing a compact, self-contained address estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
