Does anyone understand, why Hamachi is using IP addresses belonging to the UK Ministry of Defence and to the U.S. Securities & Exchange Comission (SEC)?

@goligo  In order to answer your question accurately, can you explain exactly how you are setting up and using Hamachi's VPN services?

@AshC I don't see how my local setup has anything to do with the IP address ranges used by Hamachi, but here you go: I downloaded the LogMeIn Hamachi Client from https://www.vpn.net/ . After installing I clicked on "Create a new network" and provided a network name and a password. My Hamachi client is now showing a IPv4 (25.XXX.XXX.XXX) and a IPv6 address (2620:9b::XXXX:XXXX). 

As you might know the IP address space is managed by IANA ( https://www.iana.org/numbers ) and network providers get subnets assigned they can use. So I was very puzzled to find out, that the IP addresses used by Hamachi not only do not belong to them, but as I wrote before, to governmental organizations, namely the UK Ministry of Defence and the US SEC.

You can do a whois-query yourself, to  find about the address space your IP is part of. The IANA whois service ( https://www.iana.org/whois ) tells us, which regional organization is responsible for the given address, it is RIPE for the IPv4 and ARIN for the IPv6 range. These have whois-tools on their site, you can try out  yourself: https://apps.db.ripe.net/db-web-ui/query?bflag=false&dflag=false&rflag=true&searchtext=25.0.0.0&sour... and https://whois.arin.net/rest/net/NET6-2620-2/pft?s=2620%3A%3A

@goligo  I've confirmed we are not routing through the MOD ourselves, but used a similar IP address in the same range.  This is in part to stop users from attempting to reach the MOD due to the inherent IP conflict.
