Summary

Netcraft

United Kingdom · AI-generated

business cybersecurity corporate

NETCRAFT is the autonomous system for Netcraft Ltd.

What it's used for

  • The address space is identified by the netname UK-NETCRAFT-20120228 and registrant Netcraft System Administrators, indicating a corporate network for the cybersecurity firm.
  • The AS announces 512 IPv4 addresses within a single /23 prefix and 2 IPv6 prefixes, with only 1 observed neighbour, characterizing it as a small, isolated corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate operations for Netcraft, a London-based company providing cybercrime disruption and digital risk protection services.

Notable

  • The RDAP registrant Netcraft System Administrators aligns with the AS holder Netcraft Ltd, confirming consistent ownership.
  • Netcraft acquired FraudWatch International in September 2023, expanding its cybercrime detection capabilities.
  • The inventory is compact, consisting of one IPv4 block and two IPv6 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.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
