# GnuDIP Release 2.3.5++ - Overview for End Users

This is release 2.3.5++ of the GnuDIP Web Interface.

The GnuDIP software implements a Dynamic IP DNS service. It provides clients with a static DNS name even if their IP address is dynamically assigned.

At the time of writing, this software may be obtained from SourceForge.

> For the most part, the GnuDIP Web Interface is self-explanatory. Only a few points are discussed here.

### The "Login" Page

> If there is no "Self Register" button, the site operator has chosen not to provide this capability.

### The "Self Registration" Page

> A GnuDIP site may provide an alternative "Self Registration" page. The following description is for the standard GnuDIP page.

> You must choose a domain from the list. The host name you enter will be within that domain. Your fully qualified domain name (FQDN) will be "Hostname.Domain".

### The "User Options" Page

> The button labeled "Set Quick Login URL" can be used to create a new Internet Explorer "favorite", Netscape "bookmark" or Windows "desktop short cut icon" that will allow you to go directly to the User Options page without logging in to the GnuDIP Web Interface.

### The "Current Settings" Page

> > If any of the three items below are not present, the site operator has chosen not to provide this capability.

> Wild Card
>   A user may select the option to have a wildcard DNS CNAME zone record for their domain. So for example they may put "`www.`" in front of their domain name and have this resolve to the same IP address.

> Mail Exchanger
>   A user may specify a domain to use as a mail exchanger on a DNS MX zone record. Mail Transfer Agents (MTA-s) will send E-mail for the user's domain to the mail exchanger domain host rather than the user's domain host. The user must make arrangements for the mail to be accepted there.

> Backup Mail Exchanger
>   A user may specify that the mail exchanger is only for backup use. Another MX record with higher priority pointing at the user's domain host will be added. MTA-s will attempt to use the higher priority MX record first. If the user's domain host does not respond, the MTA will send to the mail exchanger host.
