Summary
ShaneMcC Ltd
hosting business infrastructure
Nineteen IPv6 routes and five hundred IPv4 addresses, from a network with one upstream.
What it's used for
- A one-person company's network. One IPv4
/23and nineteen IPv6 prefixes announced from the United Kingdom, five hundred addresses, through a single observed BGP neighbour.
Notable
- The IPv6 announcements form a doubling staircase: a
/32, then a/33,/35,/38,/41,/43,/47,/48,/46,/45and more, each one covering the space the previous ones left. - The single IPv4 block is registered to a limited company; the abuse contact is an individual's name rather than a role.
- Two sampled addresses answer with the address in dashes under the company domain.
- The third answers under a completely different domain, with a three-letter label used for a relay host that keeps a connection open on a user's behalf.
- Three addresses were queried for reverse DNS and all three returned a name.
Interesting
- Nineteen IPv6 routes from five hundred IPv4 addresses inverts the usual proportions. Most networks this size announce one IPv6 prefix if any; this one announces more than many national carriers.
- The staircase is how you announce a range piece by piece when the pieces are not a power of two. Every step doubles, so ten routes cover what no single prefix could.
- A relay host named in reverse DNS points at chat infrastructure, which is a use that predates most of what runs on the internet now and has never quite gone away.

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.
