How to Add DNS Records

DNS records tell the internet how to handle traffic for your domain — where to find your website, where to deliver email, and how to verify your identity. This guide covers the most common record types.

How to add a record

1. Open the DNS Manager and click on the zone (domain) you want to manage.
2. Click Add Record.
3. Select the record type, fill in the required fields, and click Save.

A record — points your domain to an IP address

• Name: Leave blank or enter @ for the root domain. Enter www for the www subdomain.
• Type: A
• TTL: 3600 (or leave default)
• Address: Your server IP address

AAAA record — same as A record but for IPv6

• Name: @ or subdomain name
• Type: AAAA
• Address: Your IPv6 address

CNAME record — points a subdomain to another domain name

• Name: The subdomain (e.g. www or blog)
• Type: CNAME
• Address: The target domain (e.g. yourdomain.com)

Note: You cannot use a CNAME for the root domain (@). Use an A record instead.

MX record — directs email to your mail server

• Name: @ (root domain)
• Type: MX
• Priority: 10 (lower number = higher priority)
• Address: Your mail server hostname (e.g. mail.yourdomain.com)

TXT record — used for SPF, DKIM, DMARC, and domain verification

• Name: @ for root domain, or specific name (e.g. _dmarc)
• Type: TXT
• Address: The text value (e.g. v=spf1 include:b2b-server.net ~all)

SRV record — used for services like VoIP and Microsoft 365

• Name: Service and protocol (e.g. _sip._tcp)
• Type: SRV
• Priority, Weight, Port: As specified by your service provider
• Address: The target hostname

CAA record — controls which certificate authorities can issue SSL for your domain

• Name: @
• Type: CAA
• Address: e.g. 0 issue "letsencrypt.org"

TTL explained

TTL (Time To Live) is how long DNS resolvers cache your record, in seconds. A lower TTL (e.g. 300) means changes propagate faster. A higher TTL (e.g. 86400) reduces DNS lookup traffic. 3600 (1 hour) is a good default.
