| · | DNS Records
|
| · | Data directory
|
| Specify the directory where data files are stored (boot and zone files).
|
| The default is a directory called "data" under the directory where Simple DNS Plus is installed.
|
|
|
| · | Load primary zones on demand only
|
| Enabling this option will delay loading of primary zones until the first related request is received.
|
| In setups with many zones this can greatly improve the server startup time.
|
| Inactive zones will never be loaded, which may also improve memory consumption.
|
| · | Hosts File
|
| Simple DNS Plus can use the local hosts file as a source for DNS records.
|
| The TTL specifies how long clients and other DNS servers may cache these records.
|
| · | NXDOMAIN Redirect
|
| Typically when you open 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.
|
| 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 impossible to determine if a DNS request comes from a browser or another type of application), so you may need to use the sub-option to limit this to names starting with 'www'.
|
| And to prevent this from happening to your own domains, use the other sub-option to only redirect domains for which this server is not authoritative.
|
| Please note: Only requests which are for domain names confirmed non-existing (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 record names) will never be redirected.
