Summary

Xygnition Research

United Kingdom · AI-generated

enterprise legacy

Xygnition Research Limited (xygnition), a small private company registered in Sunbury-on-Thames, England, whose filed activity is the manufacture of loaded electronic boards. The AS announces a single /22.

What it's used for

  • One prefix, 193.93.44.0/22 (about 1,024 addresses), behind a single observed neighbour. This is an end-site network, not a carrier.
  • The prefix is registered to Xygnition Research itself, with the netname CUSTODIANDC and a UK sponsoring LIR: the space is provider-independent addressing hosted through a British data-centre operator rather than assigned by a transit provider.

Notable

  • No PTRs came back on the addresses sampled inside the prefix. That is not proof the reverse zones are undelegated, but it does mean the rDNS gives no hint of what the space carries.
  • The AS number is a low, early-range allocation, while the current holder is a company incorporated in 2016. Treat the number's age as a routing artefact, not as evidence about the present holder.

Interesting

  • The RESEARCH in the company name is part of a legal entity name, not a sign of an academic or research network. Nothing in the routing or registration suggests a research institution.

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: 442 networks and 1,778 prefixes, as published 2026-10-20. 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.
