Domain Name Host Record
What is a host record?
Host records are the connective tissue that associate domain names to IP addresses, and ultimately to things like your web site content and email. In our usage, host records include the widely used resource records (like A and CNAME) as well as the record types we’ve created for the convenience of our customers (like URL Forward and URL Frame).
What are host records for?
Host records perform several functions. They control what information your domain name connects to, and how it connects. For instance, if you own the domain name example.com and you want visitors to go to one web page if they type example.com but a different page if they type www.example.com, you achieve that by setting different host records. Host records also let you connect to your email, FTP, and other web services.
Do I need to set host records?
Most of our services automatically set host records for you—if you subscribe to our services, you may never have to touch your host records. And if you use third-party services, the service providers will tell you what records to set.
What are the best practices for different types of host records – which type of record should I use, and when?
|Record Type||Uses||Notes||IP||IPv6||FQDNi||Host Namei||URL|
|A||Hosted web site||Resolves fastest.||Yes||No||No||No||No|
|AAAA||Hosted web site||Resolves fastest.||No||Yes||No||No||No|
|CNAME||Hosted web site||Do not use CNAME for the @ record if this domain will be used for email. Resolves second fastest.||No||No||Yes||Yes||No|
|URL Forward||Redirect to new URL||RShows the URL that you forward to. Resolves more slowly than A or CNAME.||Yes||No||Yes||No||Yes|
|FRAME||Redirect to new URL||Shows this host record and domain name, not the URL you are forwarding to. Resolves more slowly than A or CNAME.||Yes||No||Yes||No||Yes|
|MX||You can use more than one MX record if your mail system supports host records.||No||No||Yes||Yes||No|
|MXE||Limit of one MXE record per domain name.||Yes||No||No||No||No|
What are the basic host records?
In our system, we always show at least three host records for every domain name:
- The www record specifies where you want visitors to land if they type, for instance, www.example.com.
- The @ (“at”) record specifies where you want visitors to land if they type your domain name without a host name, such as example.com.
- The * (“star”) record specifies where you want visitors to land if they type any other host name, such as sales.example.com.
You can add more host records if you wish.
How do I set host records?
Log in and click “Registered Domains”. Click the domain name for which you want to set host records. In the “Host Records” row, click “edit”. Use the “Type” menu and “Address” text boxes to specify www, @, and * records; add other host names and records if you wish, and click “Save Changes”.
What is the ideal setup for host records?
If your priority is letting visitors open your site quickly use as many A records as possible, plus an MX entry for the @ record, for email. However, you can mix and match record types as needed except that you should not use a CNAME record type for the @ record (it is likely to disrupt delivery of all email to the domain name).
