DNS and hosting
john
public IPs. However I really have a company DNS hosting me, by pointing
their server to my website address. How can I create my own DNS server
to point to my own website using one of my own public IPs. ?
Would appreciate any help.

ONLY your public IP space DNS. This is in addition to any DNS server you now
may have for your internal LAN.
I have to ask you, why do you want to do this? The customary configuration
is to allow a public commercial facility to host your external DNS while
maintaining your own DNS for internal LAN IPs. Most folks, and companies do
it this way. Usually only the very largest corporations with 1000s of hosts
run their own external DNS.
If it is just control that you want, there are many many sites out there
where you can control and configure your own external DNS using their
servers via a GUI interface. One such place is http://www.dns4free.com.

mail sent to them cannot be forwarded to an external internet account,
like hotmail. I thought the problem is that my DNS server is hosted by
another company and its their name server that is really on the
internet.
Please tell me how I can build those two DNS servers to host my public
IP space DNS. Would appreciate your help.

your own mail server and running into bounced mail and/or junkmail issues
with hotmail and/or other destinations. Correct? If not, just ignore...
Anyway, on that topic...
Yes, you will run into this problem with an improperly configured DNS. By
that I mean, improperly configured hosts verses MX records verses your mail
server's reported "helo" name. Also, you'll need SPF records configured in
your DNS in most cases to avoid the bounced or junkmail category.
However, the physical location of any of the factors affecting the above has
nothing to do with the end result. Your DNS can still reside at a different
physical location. You just have to make sure your DNS hosting company
configures to your needs. If they won't do that, find another one.
For mail to successfully be delivered to most large systems, they must pass
sort of a "sanity" check at the receiving end. Different values are
weighted, depending on the configuration of the receiving mail server, and
assigned a value that will result in a bounce or being relegated to
"junk/spam" status. Some of these factors are:
- DNS has a reverse lookup record (also called PTR record)
- DNS has valid MX record for mail server
- DNS has valid A record for mail FQDN (including hostname -
machinename.domain.com)
- DNS SPF record exists
- Mail server's "helo" string correlates to the DNS record
If you control the mail server, make sure the helo report uses the same name
that is configured in DNS as the hostname A record (machinename).
If you do all the above, or have your DNS host do all the above, your mail
should succeed. If you cannot get your DNS host to do their part, find
another host. As I mentioned before, http://www.dns4free.com will allow you
to manage your own DNS and do all of the above. Of course, you'll have to
learn how to do it all if you don't know now. But that would be required
even if you ran your own DNS servers at home.

This is a big deal. No one could possibly tell you how to do that in a
newsgroup. And... how you do it depends on your individual network, internal
DSN, exact domain name and configuration. If you post all of those, you
might get some useful responses.
What is your external domain name?
What is your internal domain name?
Is your present ISP really "hosting your DNS" or is it simply redirecting
web pages to your local IP?
Specifically state what you need to accomplish - everything. Not sure I have
all the answers, but you would be more likely to get some help this way.
