Summary

Mystere

United Kingdom · AI-generated

business small uk

MYSTERE is held by Mystere Matthew Southgate.

What it's used for

  • The space carries addresses for 39 DESIGN LTD, as indicated by the netname UK-GHOST-20180117 and reverse DNS entries pointing to 39networks.net.
  • The AS announces 256 IPv4 addresses across 1 prefix with 1 observed neighbour, indicating a small, self-contained business network rather than a transit or large access provider.

Notable

  • The registrant 39 DESIGN LTD differs from the AS holder Mystere Matthew Southgate, suggesting the address space may be leased or managed by a separate legal entity.
  • The inventory consists of a single /24 block (185.242.44.0/24) with no IPv6 prefixes, representing a compact, single-site address estate.

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 1,784 prefixes, as published 2026-10-19. 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.
