New in Simple DNS Plus v. 4.00

Automatic SPF records - help fight spam and phishing scams
Simple DNS Plus can now automatically synthesize SPF records for all local zones making it easy to setup and maintain SPF protection for your domains.

New option to redirect abusers (synthesize DNS records for unauthorized users)
When someone (unauthorized) from the Internet tries to resolve outside domain names via your DNS server, Simple DNS Plus can now respond with synthesized (false) DNS records, for example to redirect that person to a signup web-page or similar.
This feature is also useful when someone is incorrectly pointing their domain registration to your DNS server - for example an ISP customer who has cancelled their account but not changed the domain registration.
NAT IP alias conversion
In DNS responses to LAN clients only, this function changes A-records which are pointing to a public IP address of the NAT router to point to the corresponding private IP address of a local server.
This way, for example HTTP requests from LAN clients for local web-sites will go directly to the local web-server instead of via the NAT router (which often does not work).
IP address blocks with expiration time and comments
You can now specify how long an IP address block should be in effect.
And you can enter comments for each block, for example about why an IP address was blocked or should not be blocked for easy reference.
DNS record and zone comment fields
Enter comments for individual DNS records and zones. For example client account numbers, or reminders about what certain records do, etc.
For DNS records updated dynamically or via DHCP, the comment field will automatically contain a timestamp and other information about the update.
New Bulk Update Wizard
Find and replace an IP address in all local primary zones....
Update zone DNS server information in all local primary zones....
Promote secondary server to primary (convert all secondary zones to primary)...
"Zone Groups" for easier managements of large domain portfolios.
In the "DNS Records" window zone list, you can now arrange zones in custom groups, or by primary/secondary status.
Updated GUI
Many dialogs re-designed to be easier to use, Windows XP style controls, tabbed documents in main dialog, new wizard dialogs, etc.
Optimized cache handling
33% reduction in cache memory use, top level referral caching (faster recursion), instant cache clearing.
Miscellaneous
