DNS tells the internet where your domain should send visitors, mail, and verification tokens. On HostStack plans you will most often edit records either at your registrar (when using HostStack nameservers) or at an external DNS host such as Cloudflare.
- A — maps a hostname to an IPv4 address (common for
@andwww). - CNAME — aliases one hostname to another (useful for
www→ apex patterns depending on your DNS host). - MX — where inbound mail should be delivered for your domain.
- TXT — arbitrary strings used for SPF, DKIM, DMARC, and domain verification.
Propagation across resolvers can take from minutes to hours — combine DNS changes with patience and cache clears (see our troubleshooting article on propagation).
