TXT Records
Store verification data, SPF, DKIM, and DMARC policies.
Regular monitoring

DNS (Domain Name System) records are instructions that live in authoritative DNS servers and provide information about a domain, such as its IP address or mail servers.
An A (Address) record points a domain or subdomain to an IPv4 address. It's the most common type of DNS record, used to map domain names to the server hosting the website.
MX (Mail Exchange) records specify the mail servers responsible for accepting email on behalf of your domain. They include a priority value to determine the order in which servers should be tried.
DNS propagation typically takes 24-48 hours, although many changes are visible much sooner. The time depends on the TTL (Time to Live) value set on your records and ISP caching.
