Hi OM,

44 addresses have a domain lookup alright. Any address ending in amp.org 
is being resolved fine by hamradio.ucsd.edu name server that Brian 
Kantor looks after. If you want you can download the files ampr.org, 
amprhosts and amprnets via anonymous ftp to ftp.ucsd.edu by looking at 
directory /hamradio.

Asking and declaring a 44 affress is not merely for administration 
purposes and for duplicate avoidance. It is also practical. Any ampr.org 
address can be resolved by the amprnet DNS SERVER hamradio.ampr.org just 
like any other Internet host.

It is a very good idea for all radio Amateurs that are interested in 
promoting Amateur Packet Radio to get an IP Address from their local IP 
Coordinator and if they do not have one locally they can contact Brian 
Kantor (brian at ucsd.edu) and ask him to appoint one for your area, 
perhaps yourself if there is noone else or if he cannot be contacted or 
cannot be bothered to issue local IP addresses anymore.

If we go on and use the easy solution by issuing addresses in the  
Region of 10.x.x.x or 192.168.x.x then  theses interfaces will have no 
AMPRnet connectivity.

I think that a JNOS slip interface, especially all radio Interfaces 
should have 44 addresses.
I know that there are other ways of connectivity (i.e. by usign NAT etc) 
but all radio interfaces that use TCP/IP should definatelly have a 44 
address, otherwise we defeat the purpose of radio amateur networking.

Although the 44 network should be firewalled in all entry points so that 
non 44 hosts cannot entere the 44 network and thus key our transmitters, 
you can use MX records for e-mail, i.e you can have your slip interface 
of JNOS or the eth0 interface of  the LINUX BOX that hosts your JNOS 
have a non 44 real Internet address and have your MX records pointing 
there. Or have your MX Records pointing to your Local AMPRnet GATEWAY 
and arrange things with your LOCAL IP COORDINATOR.
