AS8577 XYGNITION

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.
