Wait. What's the objection to ULA? Is it just that NAT is bad, or is there something new?
No particular objection, but I don’t see the point.
What can you do with ULA that GUA isn’t suitable for?

ULA provide stable internal addresses which survive changing ISP for the average home user. Now, I know you can do the same thing by going to a RIR and getting a prefix but the RIR’s aren’t setup to supply prefixes like that to 10 billion of us. They are also in a specific range which makes setting filtering rules easier for everyone else. Now I would love it if we could support 100 billion routes in the DFZ but we aren’t anywhere near being able to do that which would be a requirement for abandoning ULA. Until them they have there place. Mark -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@isc.org
