How Do I Manage DNS and Advanced DNS Records?

Note: Managing your DNS with Web.com® means moving to our nameservers. When you move nameservers to Web.com®, your existing nameservers will no longer be used. As a result, websites and emails from other providers will be lost. There will also be a temporary disruption in service.

Overview

DNS and Advanced DNS (ADNS) Records are already configured to utilize your services. However, these records can be modified when needed. This option is helpful if you want to keep one of your services active and host your other service with another provider.

For example, you want to keep your email inbox active and host your website with another provider. Your Domain Nameservers must be moved to our managed nameservers to use the Advanced DNS Manager.

Domain Nameserver changes may take 24-48 hours to update throughout the internet, also called propagation. Updates may resolve faster at some locations than others because many nameservers on the internet retrieve updates at different times.

Select a record below for further instructions. 

Nameservers are the directories that match the domain with the IP address, determining how your domain is configured. Nameservers allow you to change which hosting provider controls your website and email address.

Follow the below steps when you are ready to change or modify the nameservers.

  1. Log in to your Account Manager.

  2. Select Domain Name on the left side of the page.>
    Red box around Domain Name option on left menu

  3. Select the domain name you want to change. If you only have one domain, you will be taken directly to the Domain Details page.

  4. On the domain page, go down to the Advanced Tools section.
    Red box around Advanced Tools drop-down

  5. Click Manage next to Nameservers (DNS).
    Red box around Manage link next to Nameservers

  6. Enter your nameservers, then click Save.

Nameserver (NS) Records for subdomains determine which DNS server controls the records for a domain. Pointing a subdomain host to a different nameserver allows another DNS service to manage how records on that subdomain are handled.

  1. Log in to your Account Manager.

  2. Select Domain Name on the left side of the page.
    Red box around Domain Name option on left menu

Mail Exchange Records (MX Records) are used to create a mail route for a domain name. A domain name can have multiple mail routes—each assigned a priority number. The mail route with the lowest number identifies the server responsible for the domain. Other mail servers listed will be used as backups. Without this record, you would not receive your email messages.

A CNAME (canonical name) Record is a DNS record that can create an alias for the domain and allow traffic for the domain name to be redirected elsewhere. You can only create a CNAME for a third-level domain. The Advanced DNS manager does not provide the option to create an alias for the second level.

This could create conflicts with other records and result in the loss of email or website services. If you want to redirect traffic for a second-level domain, you can review our Web Forwarding product.

TXT Records have several functions. One common function is to use the TXT record to create a Sender Policy Framework or SPF. SPF Records help stop email spammers from forging the From fields in an email. This allows the owner of a domain to designate the IP address that can be used to send email from that domain.

Need help creating an SPF TXT record? Click this site directly above entries.

Another function is to create Domain-based Message Authentication, Reporting, and Conformance (DMARC). DMARC uses DNS to publish information on how an email from a domain should be handled (e.g., do nothing, quarantine the message, or reject it).

Note: If you have a hosting package or website with Web.com® that has a Contact Form, please update/edit your existing SPF record with the record below:

v=spf1 include:spf.registeredsite.com include:spf.cloudus.oxcs.net ~all

You can only have one SPF record. Having more than one SPF record will break your email.

  1. Log in to your Account Manager.

Service Records allow users to locate a specific service on a network rather than one particular machine. An A Record is used to find a server or host, while the SRV record finds a service provided on the network. The service could be a printer, VoIP, FTP, or other similar services. They work similarly to how MX Records function, just with different types of services.

    5. Target: The name of the machine providing the service.
    6. TTL: The standard time to live field. The TTL default is 7200 (2 hours).
    7. Priority: The priority of the target host; lower value means more preferred. The priority can be any number between 0 and 65535.

Domain Name System Security Extensions (DNSSEC) add an extra layer of security to your domain. It uses a signature when trying to resolve your domain, ensuring that the connection is secure.

  • Why would I want it? DNSSEC provides added security against attacks such as cache poisoning.
  • How do I turn it on? There's a toggle at the bottom of your domain page.

Red box around DNSSEC toggle switch

  • Why can't I see the option to turn it on? DNSSEC is only available for .COM/.NET/.INFO/.ORG/.BIZ domains currently.
Note: Advanced DNS updates will take up to 2 hours to take effect. Updates may resolve faster at some locations than others because many nameservers on the internet retrieve updates at different times.

Certificate Authority Authorization (CAA) records allow you to restrict certificate providers for your domain. This gives you control over who can issue a certificate on your domain or subdomain. Your security certificate provider can give you the details on what to enter for your CAA record.

DomainKeys Identified Mail (DKIM) adds a digital signature to outgoing messages as authentication that your email address is valid. The DMARC policy indicates to your receivers that your messages are DKIM protected. It also tells them what to do if messages do not pass, are flagged as junk, or are rejected.

Note: An email address is required to configure your DMARC policy. It will be used to receive reports on authenticated messages and flagged messages, including the reasons why. The email needs to be under the same domain as the DKIM domain. If not, you must publish a DNS report record to allow it to receive reports from a different domain.
  1. Log in to your Account Manager.
  2. Select Email on the left side of the page.

Red box around Email option on left menu

  1. Select the email package you want to edit. If you only have one email package, skip this step.

  1. Click DKIM Manager to launch the DKIM Control Panel. You will then be brought to the DKIM Manager.
  2. To enable DKIM, select Configure with auto-generated keys.

  1. Next, select the DMARC policy. It is recommended that DMARC policies be introduced gradually. Begin with a setting of None, move to Quarantine, and finally to Reject. Monitor your DMARC reports at each stage to ensure messages are signed and not spoofed.
    1. None - No action needed; useful for monitoring.
    2. Quarantine - Message should be set aside.
    3. Reject - Message should be rejected.
  2. Enter the email address you would like to receive the DMARC reports at in the Send Reports to field. The email address must be under the domain that you are managing.

You have enabled DKIM, and your DNS settings will be automatically updated as long as your domain name is on our nameservers.

Note: If your domain is not on our nameservers, click the link that says View DNS TXT Record Information after you have enabled DKIM and provide these records to your nameserver host.
