Re: NOC servers with public/private ip address

["Christopher A. Woodfield" <rekoil () semihuman com>]

If you're talking about assigning RFC1918 space to router interfaces that 
transit traffic, a la @home, keep in mind that this can break PMTU-D, and 
makes for messy (and slow) traceroutes when external hosts try to resolve 
unresolvable reverse DNS entries.  

If you're talking about giving the workstations in your 
NOC private IP addresses, using NAT to access your core routers, I see no 
more a problem with that than I do with people using home DSL routers that 
utilize NAT.
