While there are multiple reasons, RFC 1918 does actually state that address space is a scare resource. The Internet has grown beyond anyone's expectations. Sustained exponential growth continues to introduce new challenges. One challenge is a concern within the community that globally unique address space will be exhausted. A separate and far more pressing concern is that the amount of routing overhead will grow beyond the capabilities of Internet Service Providers. Efforts are in progress within the community to find long term solutions to both of these problems. Meanwhile it is necessary to revisit address allocation procedures, and their impact on the Internet routing system. > There are a number of potential options for 'private' domain space.

Well hopefully DNSSEC will eventually be on by default and squatting like this will have negative consequences. There may be a need for a reserved suffix. It doesn't have to be .HOME. Rewarding bad behaviour leads to more bad behaviour. > Regards, > -drc -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
