DNS.
The system that turns your domain name into the address of the server holding your site. Changing where a site lives means changing DNS records, and nothing else about the site has to move.
Why it matters.
Two records matter to most owners: the one pointing the domain at the website, and the MX records pointing email at whoever handles your mail. Mixing those up is the classic way to take a business's email down while moving its website. Changes propagate in minutes on modern providers, not the 48 hours people still quote.
How to check it yourself.
Look up your own domain on any public DNS checker. The A record should point at your host and the MX records at your mail provider — if you do not recognise either, find out who does before anything needs changing urgently.
Questions
Before you ask.
How do I check dns on my own site?

Before you decide anything
Find out whether
you have a problem.
Most people asking about a rebuild do not need one. The free check opens your site, looks at how it behaves on a phone, whether it is secure and how old the page is, and tells you which of those apply to you.
Start with a
straight answer.
Describe the business and where it works. We come back with what we would change, what it would cost and how long it takes — or with a reason not to bother.
