From public records, looked up just now: the domain's DNS, and the registries' own records of who holds each domain name and network (RDAP).

Keep a copy with your passwords, or send it to whoever looks after your site, so everyone knows who to call.
Who to call for what
A website is usually three or four companies' work. When something breaks, calling the right one first saves a day.
- Website down or slow
- Your web host: the company whose computers hold your site. See Is my website down for everyone or just me?
- Domain about to run out
- Your registrar: where you rent your domain name, by the year. If it lapses, your website and your email stop. See Keep your domain from running out.
- Moving your site or email
- Whoever runs your DNS (the domain's address book). It's often your registrar or your web host.
- Emails not arriving
- Your email provider, named by the mail servers. Then try Email check.
- Pages wrong, or need changing
- Whoever built the site, or the website builder it's made with.
What it can't tell you
- A host behind a shield. Many sites sit behind a service that speeds them up and blocks attacks. Then we see that service's network, not the host behind it.
- Hidden registrations. Some registries don't publish the registrar or the renewal date. Your own account with the registrar always has them.
- Who owns the website. Owners' names are usually private, and we don't look for them.
- What the site is built with, every time. We only name a builder when the home page shows clear signs. See What is this website built with?
How to use it
- Type the website's address, like YourWebsite.com. Any site works, not only your own.
- Press Look it up. It takes a few seconds.
- Read down the rows: each says who runs that part, and when to call them.
- Press Copy the message and keep it with your passwords, or send it to whoever looks after your site.
What your results mean
- Where the website is hosted
- The company that owns the network your site's address is on, exactly as the registry records it. Usually your web host.
- Domain name registered with
- Your registrar: the company you rent the name from, and the date it's paid up to. Put that date in your calendar, a month early.
- DNS (name servers)
- Where your domain's address book is kept. Changing where your website or email lives happens here.
- Email handled by
- The mail servers (MX records) that take email for your domain. Their names usually show your email provider.
- Built with
- The website builder or software that made the site, when the home page shows clear signs of it.
- We couldn't tell
- The public records or the page didn't say. Your own accounts with your host and registrar always have the answer.
When to use it
- Your web person has left or stopped answering, and you need to know who to call.
- You've taken over a website, like a new club secretary or office manager.
- Before your domain renews, to see who it's with and the date.
- Your site or email is down, and you're not sure whether to call the host or the email provider.
Why it matters
- If nobody knows who holds the domain, a renewal can be missed, and the site and the email stop with it.
- Calling the right company first saves hours on hold with the wrong one.
- A written copy means the next person in your job doesn't start from scratch.
Go deeper: Domain name expired? Get it back and keep it. If it lapses, your website and email stop together. Three checks a year stop it.
