CIDR format is specified as address/length, so 128.0.0.0/18 is the only sanctioned way to specify this per RFCs. The fact that Cisco routers still require the crufty masks and wildcard bits not withstanding. Juniper routers use only proper CIDR syntax. FreeBSD will accept either for IPv4 (ifconfig(8)). In the world of IPv6, only CIDR notation is used, even by Cisco. We really should only be used CIDR notation unless we are explaining the legacy use of masks. Class A/B/C has been obsolete for almost a decade and really, really should go away.
Maybe we should mention somewhere that the old class A/B/C networks have been obsoleted by CDIR and not simply remove all references to it. I also think we should explain a bit about how CDIR works, as someone suggested. You can also point people to http://www.3com.com/other/pdfs/infra/corpinfo/en_US/501302.pdf which explains a lot about CDIR, subnetting and whatnot. Just some thoughts. //Niclas -- _______________________________________________ cvs-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/cvs-all To unsubscribe, send any mail to "[EMAIL PROTECTED]"
