Question ID: 95717
How can I obtain an IP number, and then run a DNS for that site.  Is
it possible to obtain one ip number (for an individual person), and
then map it to a name?  Are there any dns that will list your ip
number on their DNS?

Are you looking for a way to have a DNS name attached to a personal IP
address?

For example, you want: myname.myhouse.com to resolve to the IP address
on your home computer?

If so, do you have a static or dynamic IP address and do you currently
own a domain name that you want to use to point to the IP address?

are you looking to run a webserver and have people be able to go to
www.yourname.com and have it point to a webserver? if so, would you be
running the server yourself or would you have someone else do it? is a
dedicated ip required (usually it is not)? have you already registered
your domain name and are just looking for dns services, or do you need
to register a domain?

I want to run a webserver, and a DNS server.  I have my own ip-address
given to me by my isp, but I think that the ip-number cannot be
remapped by another dns.  Therefore, I would like to obtain an
unregistered ip-number.  I do have a domain name.

It is actually not that hard to run a webserver and a DNS server for
your home computer if you have a static ip address.

To run a dns server, you would need to download one of several
freeware dns server programs. Download.com can help with this [
http://download.com.com/3120-20-0.html?qt=dns+server&tg=dl-2001 ]. The
way DNS would work for you is that when you registered your domain
name (I assume you have one, if not they are cheap to register at
www.domainmonger.com), you can specify what DNS server address you
would like to use for name resolution. You would then enter your ip
address for your dns server that you run at home. This server would be
configured to provide the ips for the various servers you are running
(www.yourdomain.com, ftp.yourdomain.com etc).

If your isp gives you a static ip address, (most will do so for a
small fee) this is all you need to do. If you need to know how to
setup a webserver as well as dns, I suggest you look at an answer I
gave recently [ https://answers.google.com/answers/main?cmd=threadview&id=95508

For some help on actually configuring the DNS server itself, I
recommend the following links:

Isn't the ip address given by my isp already using a dns to do reverse
and forward mapping of ip addresses, and wont that create a conflict
when using another dns?

Clarification of Answer by funkywizard-ga on 01 Nov 2002 22:05 PST
When people do a reverse dns lookup on your ip address, it will indeed
map to something that your isp has designated, for example here is a
traceroute:

C:\>tracert 24.237.4.113

Tracing route to 113-4-237-24-cable.anchorageak.net [24.237.4.113]

This clearly shows that 113-4-237-24-cable.anchorageak.net will
resolve to the ip address 24.237.4.113, and that doing a reverse
lookup on the ip 24.237.4.113 will get you
113-4-237-24-cable.anchorageak.net.

However, for your use, this is not necessary. In the example above,
this ip address is used to host my website, akddr.com, along with
several other websites, such as akghetto.com and aksearch.net. Any
number of domain names may point to a single ip address, and in fact
more than one dns server may point to an ip address. If you absolutely
must have a reverse lookup respond with your server address, you will
have to contact your isp and request that they change their reverse
lookup table. In order to set your own reverse lookups, you will need
to own your own class c ip address range (x.x.x.y, where y is any
value 0-255, and the x.x.x. is assigned to you specifically).

None of this will affect the performance of running your own dns
server to maintain a list of websites that reference your server. for
example, www.akddr.com will resolve to 24.237.4.113 even though the
isp maintains that the reverse lookup of 24.237.4.113 will not point
to www.akddr.com. All that must be done is to inform your domain
registrar of which dns server you would like to use for resolving your
domain names.

I trust this answers your question, but if it does not, do not
hesitate to request further clarification.
