I've noticed a lot of users from different ISPs appear to have local LAN IP-addresses in the range 25.0.0.0 - 25.255.255.255. But according to RIPE, this network belongs to "DINSA, Ministry of Defence"?
If I try to ping any IP in this range, my router immediately drops the packets saying "Destination Host Unreachable".
This network is not listed in Wikipedias list at http://en.wikipedia.org/wiki/Reserved_IP_addresses
So should I consider this network reserved, or is it possible real IPs on the Internet can have IPs in this range?
