Domain
It is the name you register. Registration does not publish the website or configure every service automatically.
What is DNS?
You remember the name. DNS helps find the destination.
DNS relates domain names to destinations and service information. That is why websites and email can share a domain while working in different places.

One name can use services in different places.
Each record has a job.
Choose what you want to do. Record names make more sense when you know what they are for.
A and AAAA specify network addresses.
An A record points to an IPv4 address; AAAA does the same for IPv6. Use the address provided by the service receiving the visit.

Service address
CNAME connects one name to another.
A subdomain can use a destination name supplied by a platform. CNAME takes a hostname, not an IP address. Check the service instructions before editing.

MX identifies who receives email for a domain.
Your website and email can use different providers. Changing or deleting MX records can affect incoming mail without changing the website.

Email service
TXT publishes text information.
Services may request TXT records for configuration checks or email policies such as SPF. Each value must match its purpose and service instructions.

Caching and TTL
Answers can be cached for a period. TTL guides their lifetime, and different queries can see changes at different times.
What to know before you choose.
Is changing DNS the same as transferring a domain?
No. DNS changes affect records or zone management. A transfer changes the domain’s registrar.
Do all changes take the same time?
No. Caching, TTLs, resolvers and the type of change all matter. There is no single fixed time for every change.
How can I avoid disrupting email when changing my website?
Keep the current records and identify website and email destinations. Change only what is needed, then test both services.
