How to: Edit DNS records (A, AAAA, CNAME, MX, TXT, SRV)

This article will show you how to Add and Edit DNS records in your Hover account. The DNS zone file in your Hover account only applies to your domain if it's pointed at the Hover name servers ns1.hover.com and ns2.hover.com.

If you need to change your name servers, please see: How To: Change your nameservers (DNS Servers)

By the same token, if you're using another company's name servers, such as your website hosting company, you'll need to add and edit the DNS records through your hosting company account where that DNS zone file is managed.

You should not change your DNS records unless directed by your hosting company, or if you are familiar with configuring zone files.  If you are unsure whether or not you need to edit your DNS records, don't hesitate to contact a customer adviser for assistance at help@hover.com or by phone at 1-866-731-6556.

 

To manage DNS records, follow the steps below:

  1. Log into your Hover account at: https://hover.com/signin
  2. If you have more than one domain name listed in your account, choose Domains from the Your Account menu.

  3. Select the domain from your list, or choose Edit DNS from the Edit menu.

  4. On the DNS page, you can manage DNS records for the selected domain name.

The next steps depend on the record type that you want to edit or create.  Details for each type can be found below.

Note: Hostname refers to the prefix before the domain name.  To create a Blank record, use an @ in the Hostname field. This represents an empty prefix (so the name exactly matches the domain name; for example divapirate.com). The @ hostname is also referred to as the the root of the domain. An * (asterisk) in the Hostname is a wildcard, and represents any prefix.  For example, creating a record for *.divapirate.com will point <any prefix>.divapirate.com at the IP address provided.

 

A (IPv4) and AAAA (IPv6) Records

An A Record, or AAAA Record, is used to point a hostname at an IP address. This record type can be used to point your domain name at your web host or for creating subdomains which point directly to an IP address.

To create a new A or AAAA Record, follow these steps:

  • Click on Add A Record.

    save image

  • Select the Record Type A.  Enter your hostname, and then type the appropriate IP address in the IP Address text box. You can leave TTL at the default setting. 

    Click Add Record.

    save image

    OR
  • Select the Record Type AAAA. Enter your hostname, and then type the appropriate IP IPv6 address in the IP Address text box.

    Click Add Record.

CNAME Records

A CNAME record, or Canonical Name record, is a pointer of one name to another.  A CNAME record points a hostname to another name that is already created for a server or system.  Canonical means expected or real name.  These records are pointing a name you created at the "real" name for the server or system.

This is useful when running multiple services (such as an FTP and a webserver) from a single IP address. Each service can then have its own entry in DNS (such as blog.mydomain.com or ftp.mydomain.com).

You may also be requested to enter a CNAME record to verify domain ownership for online services such as Google Apps

CNAMEs should only be used if you can't use an A Record.

Note on CNAMES: A blank (@) CNAME record will cause other blank records to fail, such as MX records, or blank A records. This can have a negative impact on the resolution of your website or sending/receiving of email.

To add a new CNAME record, follow these steps:

  • Click on Add A Record.

    save image

  • Select the Record Type CNAME from the drop down menu.  Enter your hostname (which creates the subdomain), and then type the appropriate target hostname in the Target Host text box. You can leave the TTL at the default setting.

    Click Add Record.

    save image

 

MX Records

A MX record or Mail Exchange record specifies how e-mail should be routed.  The MX record points to the servers that should receive e-mail for the domain.

In simple terms, the MX record allows the rest of the world to know where your email needs to be delivered.  The default setting points your domain to Hover's mail system.

Each MX record contains a host name and a numeric priority.  The lower numbers have higher priority.  Priority 0 is highest priority.  Setting priority is useful if the e-mail service uses secondary servers.  Secondary servers are usually given lower priority because they may be operated externally, not have direct access to the primary e-mail storage, have less Internet bandwidth, among other reasons.

To create an MX record for your domain enter @ as the hostname.  If you are creating an MX record for a sub domain, then you can enter your sub domain into the Hostname field.

To add a new MX record, follow these steps:

  • Click on Add A Record.

    save image

  • Enter @ as the Hostname (unless otherwise instructed by your email provider), select MX from the Record Type drop-down list, enter a priority, and then type in the Hostname of your email service (your email provider will be able to tell you what hostname should be used).

    Click on Add Record.

TXT Records

TXT records allow users to associate some text with a hostname.   Originally TXT records were created to add arbitrary human-readable text to DNS records. Today TXT records have a number of practical uses, one of which is to define Sender Policy Framework (SPF) information which can be used by multiple e-mail technologies to assist in identifying the actual sender of an email.

 

To add a new TXT record, follow these steps:

  • Click on Add A Record.

    save image

  • Select the Record Type TXT from the drop-down list, enter your Hostname, and then type in the value of your TXT record. In this example, there is an example SPF Record for Google.

    Click on Add Record.

    save image

 

SRV Records

An SRV record is a service record which specifies information on available services.    Services such as Google Apps may require you to create SRV records.  

SRV records have the following form:  _Service._Protocol.DomainName TTL Class SRV Priority Weight Port Target

The Class is always set to IN and the TTL is set automatically by our DNS server.

To add a new SRV record, follow these steps:

  • Click on Add A Record.

    save image

  • The example below will create an SRV record with the following values:

    Hostname:  _xmpp-server._tcp (xmpp-server service over the tcp protocol)
    Record Type:  SRV
    Priority:  5
    Weight:  10
    Port:  5269
    Destination Hostname (Target):  xmpp-server.l.google.com

    You can leave the TTL set to the Default settings.

    Click on Add Record.

  • Click on the Edit option to the right of the DNS record you wish to edit.

    save image

To Delete an existing record, follow these steps:

  • Click on the Green X to the far right of the DNS record you wish to delete. 

    save image

  • You will be giving the chance to confirm this action, or cancel it. If you do wish to delete this DNS record, click Delete.

    save image

 

Bulk DNS Management

DNS records can be edited in bulk for multiple domain names instead of editing records for each individual domain name.  To edit DNS records in bulk, follow these steps:

  • Use the check boxes to select multiple DNS records. Then, using the Bulk Edit menu above, choose from the available bulk edit option for your selection.

    save image
  • You can sort the DNS records by clicking on the headings Type, Host, Value, and TTL.

    It would be great if Hover added a "Comment" field to each entry where you as a user could add an optional comment / reminder describing each entry that you make. That would help in the future when you've totally forgotten why specific entries were made!
