AS42973 M247 UK LtdASN lookup: IP ranges, prefixes and network type
AS42973 is the autonomous system number (ASN) announced by M247 UK Ltd. It announces 66 prefixes, 93,952 IPv4 addresses in total. Every address inside those ranges is routed by this operator, which is what makes the number the shortest answer to who runs a given address.
AS42973 at a glance
| Organisation | M247 UK Ltd |
|---|---|
| Autonomous system | AS42973 |
| Network type | VPN operator |
| IPv4 prefixes | 66 |
| IPv6 prefixes | 0 |
| IPv4 addresses | 93,952Summed across every announced prefix. IPv6 is not counted; the numbers are meaningless at that scale. |
| In known VPN ranges | 0 of 66 prefixes |
| In known datacenter ranges | 0 of 66 prefixes |
The last two rows are a second opinion, counted against the X4BNet VPN and datacenter range lists rather than read off the operator name. A network with most of its prefixes in the VPN list is carrying anonymised traffic whatever it calls itself.
Sample prefixes
The largest ranges M247 UK Ltd announces, biggest first. These are a sample and not the full routing table: 66 prefixes do not fit on a page, and the ones worth showing are the ones most traffic comes from.

What AS42973 means for detection
M247 UK Ltd runs anonymising infrastructure, so traffic from these addresses was deliberately routed to hide where it came from. Our engine classifies them vpn, sets anonymized, and returns them as a positive VPN detection. It says nothing about intent, and most people using a VPN have an ordinary reason for it. What it does say is that the location on the address is the exit, not the person, which is the whole point of a location attestation refusing to accept it.
The verdict for a single address is never settled by the ASN alone. It is the starting point, and IP Detection adds range membership, behaviour and history on top of it before it answers.
