[44net] reverse dns

Hi to the group. I am helping a group that want to start a fast speed wireless network in the 5.8ghz for the bakebone and 2.4 ghz/900 mhz for the local network and mesh. they will annonce by BGP the subnet they were allowed. Of course they will use a DNS for many of the service they will have on the network. They are wondering how will reverse DNS will sork and if it is possible to change/add the reverse dns names of the machine. Thanks Pierre VE2PF
