Domain & DNS
Understand domains, DNS records, nameservers and propagation.
DNS (Domain Name System) is the internet's phone book — it translates domain names into IP addresses so browsers can load websites.
DNS propagation is the time it takes for DNS changes to spread across all DNS servers worldwide — usually 24 to 48 hours.
An A record is a DNS record that maps a domain name to an IPv4 address, telling browsers which server to connect to.
A CNAME record creates an alias that points one domain name to another domain name instead of directly to an IP address.
An MX record specifies which mail servers are responsible for accepting email for a domain.
A TXT record stores text information in DNS, used for domain verification, SPF, DKIM and other purposes.
SPF, DKIM and DMARC are email authentication standards that protect your domain from email spoofing and improve deliverability.
Nameservers are the DNS servers that hold the authoritative DNS records for your domain and answer queries about it.
Learn how to find out when a domain expires and how to set up auto-renewal to avoid losing your domain.
Learn how to connect your domain name to your web hosting using A records, nameservers or CNAME records.
