[DNS/NAMED] What is the SOA?

BxBoy · 03-04-2003, 09:47 PM

Hi, can someone explain the SOA in the DNS domain zone file to me? (specifically this part)

Quote:

$TTL 3D
@ IN SOA ns.bxboy.com. bxboy@bxboy.com. (
200208231 ; serial, todays date + todays serial #
8H ; refresh, seconds
2H ; retry, seconds
4W ; expire, seconds
1D ) ; minimum, seconds

What does the above numbers mean? btw, those are my current settings for my DNS server, are they good?

Thanks.

Here is a site that I fould to be rather helpful when I was trying to setup a DNS server. It explains a good bit about setting one up and what different parts mean. here
