Maybe I'm not fully understanding DNS traffic... please let me know if I'm
off-base with this...
I thought that every time a user visits your site, your DNS server gets
queried for information. That happens only once per unique visitor since
after the first successful query, the information is pretty much set for the
entire session - that is future hits from the user during the session do not
need repeated DNS queries.
That's one part of DNS traffic, the other part is SOA information, which I
really don't have a clue how it works. Do the main DNS servers hit your DNS
server according to the refresh value in your SOA record? Is it the
Expiration or the TTL value?
If anyone can shed some light on this, I would greatly appreciate it.
Thanks.
