DNS Help

[Daniel Siemens]

Another option is if you have a friend with DNS servers that can create
and maintain the zone for you.   You can get together with them and buy
them a beer, the creation of zone and a few hosts is a trivial task in
most systems.   With dynamic IP's this will be a bit more effort.     

One of the problems that I would expect is the reverse lookups on the
mail servers failing.   Many of the email services will do a reverse
lookup on incoming email connections to verify that the mail is coming
from the domain in the email.   With ISP's using Classless Internet
Domain routing (CIDR), they have to create reverse DNS records as they
own the block of IP's.   The logic is this; when the receiving mail
server does a reverse lookup and sees that sbcglobal.net owns the ip's
and it's reverse DNS is adslIpaddress.kc.sbcglobal.net it expects a
sbcglobal.net email.  I know SBC will create a PTR record for you if you
have static IP's.   I don't know how they will do this for you with a
dynamic IP.   Without these records, expect some email to fail.   AOL
comes to mind.

Well Rusty, why do you use free webmail?  If I am running a 
non-commercial site to learn some stuff and there is a free DNS service 
and I can get a cheap domain, why wouldn't I want to use the cheap and 
free combination?  I've done some stupid and expensive stuff in the past

that I am now recovering from and I don't have a lot of duckets to throw

around.   My fastest PC is a PIII-500.
