Summary

DSNET Ltd

United Kingdom · AI-generated

hosting business uk

DSNET-CSP is operated by DSNET Ltd.

What it's used for

  • The address space carries hosting and network infrastructure services, evidenced by netnames UK-DSNET-20020704 and DSNET-UK-CSP134 and the registrant DSNet Hostmaster Team.
  • The AS announces 768 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web/API endpoints and network infrastructure services provided by DSNET Ltd, a UK-based company offering hosting, RIPE LIR/IP services, and BGP consulting.

Notable

  • Registrants DSNet Hostmaster Team and DSNET Ltd align with the announcer DSNET-CSP.
  • The address inventory is compact, consisting of two contiguous IPv4 blocks in the 81.90.134.0/23 range and a single /32 IPv6 prefix.

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.

Reputation

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: 440 networks and 1,773 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.
