How to check a domain DNS

Checking a domain’s DNS means finding out where it currently points. It is the first step whenever a site will not open, e-mail stops arriving, or you have just transferred a domain and want to confirm it is pointing to us.

Checking the domain’s nameservers

Nameservers decide who controls the domain’s DNS. Look them up in one of these free services, entering only your domain:

Domain type	Where to check
.co.mz · .ac.mz · .org.mz	whois.mz — the Mozambican national registry
.com · .org · .net and others	lookup.icann.org — the official ICANN lookup

Look up the WHOIS of a domain

yourcompany.com

Shows the registrant, the dates, the registrar, the status and the nameservers.

Look for the Name Server line in the result (sometimes shown as NS). If the domain is hosted with us, it should show the four MozOut nameservers below.

Is my domain pointing to MozOut?

If the lookup returns these four names, it is correct:

    dns1.mozout.com

    dns2.mozout.com

    dns3.mozout.com

    dns4.mozout.com

The order they appear in does not matter. If other names show up — from your previous registrar, or another provider — the domain is not yet using our DNS.

Checking where the site and e-mail point

Nameservers say who manages the DNS. Records say where things point. Check them with tools such as dnschecker.org or whatsmydns.net, selecting the record type:

Record	What it does	What you should see
A	Where the site lives	The IP of your hosting server
CNAME	The www of your site	Points to the main domain
MX	Where e-mail goes	Your domain, or your mail provider
TXT	Verifications and SPF	Anti-spam rules for your e-mail

Tip: tools like whatsmydns.net query from several countries at once. If some locations show the new value and others the old one, the change is still propagating — you only need to wait.

I just made a change and see no difference

A DNS change is not instant worldwide. Every server keeps the previous answer for a while before asking again. Changing nameservers takes longer than changing a record inside the zone.

While it propagates, it is normal for the site to open on one computer and not another. If it is still different after 24 hours, check that the change was actually saved — and only then open a support ticket.
