Non-existing Domains

•	Redirect requests for non-existing domain names

•	Requests for A-records (IPv4) Enter the IP address to redirect to.

•	Requests for AAAA-records (IPv6) Enter the IP address to redirect to.

•	Additional TXT-record explaining synthesized response Enter a short text explaining why the client is being redirected. This will be visible when someone uses diagnostics tools such as NSLOOKUP, DIG, and other DNS lookup tools.

•	Exceptions... Click this button to specify the following exceptions:

•	Only redirect domain names starting with 'www' Limit redirection to typical web-site domain names.

•	Do not redirect domain names that belong to local zones (authoritative) Limit redirection to domain names other than your own.

•	Do not redirect these domain names and their sub-names Limit redirection to domain names other than these.

•	Do not redirect queries from the following IP addresses Limit redirection to queries from other IP addresses than these.

Background:

Typically when you enter a non-existing domain name in a web-browser, you either get an error page, or you are redirected to some search web-site controlled by the web-browser company or possibly your ISP.

This of course happens all the time because of misspellings and bad links on web-sites.

Now you can take advantage of those failed requests (from any client configured to use your DNS server) by redirecting them to your web-server instead of giving this traffic to the browser companies.

This option redirects all recursive DNS requests for non-existing domain names to a server IP address which you control.

This gives you a unique opportunity to present your own custom search page, a domain sale offer, a marketing message, an intranet site, or anything else you can think of.

IMPORTANT: This function redirects ALL DNS requests for non-existing domain names (it is not possible for the DNS server to tell if a DNS request comes from a browser or another type of application), so you may need to use the exception options to limit this.
For example you may want to setup an exception for the IP address of your e-mail server so it won't try to deliver (otherwise failed) e-mails to your web-server's IP address.

NOTE: Only requests which are for domain names confirmed not to exist (NXDOMAIN) will be redirected - not any other error type conditions.

Domain names where the first 4 name segments resemble an IP address (reverse and RBL/DNSBL record names) will never be redirected.
