// GOOD QUESTIONS

Frequently asked

What is DNS?

DNS is the internet’s address book. It turns a domain name (like 365techies.co.uk) into the actual server addresses that make your website load and your email arrive. If DNS is wrong, your site or email can break.

What do these records mean?

In short: A/AAAA point your domain to your website’s server; MX point your email to the right mail servers; NS are the nameservers in charge of your DNS; and TXT hold things like SPF and domain-verification records.

Is it safe to look up my domain?

Completely — DNS records are public (every mail and web server reads them). We only read them, live, and nothing is stored.

My records look wrong — can you help?

Yes — DNS mistakes are a common cause of broken email and websites. We set up and fix DNS, move sites, and sort business email for homes and businesses across Dorset. Get in touch.

// HOW IT WORKS

How to check your MX and DNS records

To check your MX and DNS records, enter your domain into this free DNS lookup tool and it reads the live A, AAAA, CNAME, MX, NS and TXT records over secure DNS-over-HTTPS, showing your mail servers (MX) and website settings in seconds.

Step by step

Enter your domain — Type your domain (for example yourdomain.co.uk) into the lookup box — you can paste an email address too and it will use the domain after the @.
Run the lookup — Click 'Look up records'. The tool queries live DNS over a secure connection (Google DNS-over-HTTPS).
Find your MX records — In the results, the 'Mail servers' card lists your MX records — these decide where your email is delivered.
Check the other records — You'll also see A/AAAA (website server), NS (nameservers) and TXT (SPF and verification) records for the same domain.
Spot anything missing — Empty MX or missing SPF in TXT is a common cause of email problems — if a record looks wrong, that's usually where the fault is.

Good to know

What are MX records and why do they matter?

MX (Mail eXchange) records tell the internet which mail servers handle email for your domain. If they're missing or point to the wrong servers, your email won't arrive — so they're the first thing to check when email breaks.

Why does my domain show no MX records?

Either email isn't set up for that domain, or the MX records were removed or never added — both stop email being delivered. Check with whoever hosts your email or DNS, and add the correct MX records they provide.

Does this show the same MX records everyone else sees?

Yes — DNS records are public and this tool reads the same live records every mail and web server uses, so what you see here is exactly what governs your real email and website.
