Website DNS
An A record connects a domain host such as @ or www to an IPv4 address. Changing it sends traffic for that host to a different server after cached DNS answers expire.
Host to IPv4Example: @ to 192.0.2.10.
Each host is separate@ and www may differ.
TTL controls cacheOld answers can persist.
What it controls
The root domain is commonly represented by @. Subdomains use labels such as www, shop or app. Each can point to the same or a different valid public IPv4 address.
Change the record
http://, a hostname, port or path.Common problems
Changing @ does not automatically change www. The destination server must also be configured to answer for the domain and provide its HTTPS certificate. Mail may rely on a separate mail A record, so do not alter it when moving only the website.
