And how if you can =) You _can_ delegate the /20 as a single delegation using the CNAME trick. But I recommend _not_ doing so. Just do it with 16 separate delegations and things will go smooth and fine. If you are manually typing in zone files, sure, it's a little more typing. If you are generating them from a database, then you'll have to tweak the script a bit. And if you have separated authoritative (for in-addr.arpa at least) servers not doing resolving, then you can probably get away with configuring it as a /16 zone where the delegation points to, though you won't be able to further re-delegate from there as /24. If you are wanting this because you want to re-delegate /24's, then I guess you are in a pinch as your choices then are to use the CNAME trick or do the next delegations as /32 (and of course you are all out of delegation points after that). -- ----------------------------------------------------------------- | Phil Howard - KA9WGN | Dallas | http://linuxhomepage.com/ | | phil-nospam@ipal.net | Texas, USA | http://ka9wgn.ham.org/ | -----------------------------------------------------------------
