Free DNS Tools Home
If you need to research Domain Name Server (DNS) information on the Internet, then you'll find the tools provided here to be very useful.
Using these tools you can see where an IP address resolves (Reverse DNS) in order to track spam; find out information about your own domain, such as who is handling your DNS Name-Server (NS) requests; verify the current state of your Mail-Exchanger (MX) records; or search and review Sender Policy Framework (SPF) records for any registered domain.
If you have a web site where contact email addresses are displayed, then you should also consider taking advantage of our Email Address Encoder to help you hide your email address from address harvesting spiders. Keeping your address hidden from these email address harvesting scripts will greatly reduce the amount of Spam you'll receive in the future and may also gradually reduce the amount of spam you now receive as well.
