MX stands for Mail eXchange. MX Records tell email delivery agents where they should deliver your email. You can have many MX records for a domain, providing a way to have redundancy and ensure that email will always be delivered.
I've just rolled out a new feature for DNSimple called WHOIS Privacy Protection. For DNSimple customers that register with us or transfer domains into our system we can now make your WHOIS information private by putting a third-party in between you and spammers. For $8.00 per year per domain your email address and physical address will no longer be shown in WHOIS output. Email will be routed to you through a proxy email address.
As of yesterday, DNSimple now supports NAPTR records and domain registration and transfer of TLDs that require extended attributes through the API.
The DNSimple web site will be taken offline tonight for a short maintenance. DNS resolution should not be affected, although new records make take a few minutes longer than normal to show once the system is reactivated. We will post updates here as they become available. Thank you for your patience.
CNAME stands for Canonical Name. CNAME records can be used to alias one name to another. For example, if you have a server where you keep all of your documents online, it might normally be accessed through docs.example.com. You may also want to access it through documents.example.com. One way to make this possible is to add a CNAME record that points documents.example.com to docs.example.com. When someone visits documents.example.com they will see the exact same content as docs.example.com.
