Pointing a domain to rexguard
Each domain name of your site (for example example.com and www.example.com) needs two things in its DNS: a TXT record that proves it's yours, and records that send its visitors to us. You make both where your domain's DNS is managed (your registrar or DNS provider).
1. Add the site in the portal
In the portal, open Sites → Add a site and enter the domain names and your server's address. The site's page then shows the exact records for each domain name.
2. The TXT record
| Type | Name | Value |
|---|---|---|
| TXT | _rexguard. + the domain name, e.g. _rexguard.www.example.com |
the value from the portal (the same for all your domains) |
The record proves the domain is yours. It can stay in place afterwards.
3. Pointing the domain to us
The domain itself (example.com, a zone's apex) gets A and AAAA records:
| Type | Name | Value |
|---|---|---|
| A | example.com |
185.208.201.248 |
| AAAA | example.com |
2a10:9c80::185:208:201:248 |
A subdomain (www.example.com, shop.example.com) gets a CNAME record instead, to edge.rexguard.net. That name always points to our current servers, so you never need to change it. The A and AAAA records above work for a subdomain too.
Remove any other A, AAAA or CNAME records of the domain name, otherwise some visitors would skip the protection.
4. Waiting for DNS
We check DNS every few minutes, and you can press Check now on the site's page. A change in DNS usually shows within minutes, sometimes within hours (as long as the old records' TTL). Once we find both records, and once your email address is verified, the domain name shows online: within a few minutes we get its certificate and the protection starts.
Afterwards we look once a day whether the domain still points to us; if it doesn't, the site's page and an email tell you which records to put back.
