The most common record types
Record
Purpose
Example value
A
Points a domain or subdomain to an IPv4 address
203.0.113.42
AAAA
Points to an IPv6 address
2001:db8::1
CNAME
Alias one name to another
shop.example.com → example.myshopify.com
MX
Routes email to a mail server
10 mail.example.com
TXT
Stores arbitrary text; used for SPF, DKIM, site verification
v=spf1 include:_spf.google.com ~all
NS
Delegates a zone to nameservers
ns1.namebright.com
A records
An A record maps a hostname to an IPv4 address. You use A records when pointing a domain or subdomain at a specific server:
example.com → 203.0.113.42
www.example.com → 203.0.113.42
Most domains use two A records: one for the root ( @ ) and one for www .
MX records
MX records tell other mail servers where to deliver email sent to your domain. They require a priority number (lower = higher priority) and a hostname, not an IP address:
10 mail.example.com
20 mail2.example.com
If both mail servers are equivalent, use the same priority on both.
TXT records for email authentication
TXT records carry SPF , DKIM , and DMARC policies. These three records together tell receiving mail servers whether to trust email claiming to come from your domain.
