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. -C On Tue, Aug 14, 2001 at 04:59:34PM -0700, Roeland Meyer wrote: > > The demonstration is easy. > > 1) Convince them that it is really no-goodnik to show private addrs on the > Internet. > 2) then make them believe it religiously. > 3) then show them a traceroute and explain that everyone on the planet has > traceroute. > > The only reasonable conclusion, from that sequence, is that ALL routers and > routing hosts need a static IP addr. > > |> -----Original Message----- > |> From: R Z [mailto:[email protected]] > |> Sent: Tuesday, August 14, 2001 2:50 PM > |> To: [email protected] > |> Subject: NOC servers with public/private ip address > |> > |> > |> > |> Hi, all, > |> > |> We are an ISP with some internet routers.
