If you get the right software Win32 DNS doesn't need a lot of machine either. I run win2k on a dual p150 and a ppro200. Both machines only have 128MB RAM, I run Simple DNS Plus by jhsoft.com, no problems, that's with running a small ISP and hosting over 200 domains in DNS. Plus the software is very affordable, $79 for 25 zones, $149 for unlimited.

Your own server should NOT be noticably slower unless it is not configured correctly. Without a forwarder to use, lookups could be slightly slower at first, but once you use it a bit, it will build a decent lookup cache of it's own, then it should be faster than using any external site or forwarder. From Scott's site, it appears that the osirusoft.com sites have a TTL of 43200, so once you do a lookup, all subsequent lookups for that same IP should be served from your local cache (at least for the next 43200 seconds). If you are stuck on win32 platform, you'll need a fairly decent machine to make up for the GUI, but a VERY inexpensive, high performance DNS resolver can be built with FreeBSD/BIND on VERY modest hardware (steal your kids p233, stuff some more RAM in it and go). Our fastest DNS server is a 400Mhz PII, slowest is a 200. We are running 16 IP4 based tests on each email right now. We handle approx 20,000 messages/day. Declude is pointed at a FreeBSD4.7/BIND8 P400 Machine for doing it's DNS test lookups. This machine's average processor use is like 4%. It's hardly breaking a sweat. Unless you are generating some SERIOUS DNS traffic, IMO doing zone transfers is unnecessary extra work. - Tony --- [This E-mail was scanned for viruses by http://www.intouchmi.com] --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
