Summary

xilo

United Kingdom · AI-generated

hosting business uk

The AS handle A4N Network Services is held by xilo Ltd.

What it's used for

  • The address space carries static IP allocations for hosting clients, evidenced by reverse DNS entries such as 93.121.32.0.ip.static.as44574.net and netnames like UK-XILO-20120911.
  • With 89,088 IPv4 addresses announced across 23 prefixes and only 2 observed neighbours, the network functions as a hosting provider rather than a transit carrier.
  • Traffic from this AS consists of web servers, virtual private servers, and domain name registration services operated by xilo for its business customers.

Notable

  • Registrants for all sampled prefixes list xilo Ltd. and Network Services Hostmaster, aligning with the AS holder.
  • The address inventory is fragmented into 23 IPv4 prefixes, including large blocks like 93.121.0.0/17 and 151.249.0.0/18, alongside numerous smaller /22 and /24 allocations.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,773 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.
