Subreg DNS setup
If your domain is registered at Subreg, connecting it to Redirect Supply means changing a few records in Subreg’s DNS zone. Your domain stays at Subreg, and your registration and email don’t change. It takes about five minutes, plus a short wait while the changes spread.
Before you start
You need two things ready before you open Subreg.
Add the domain in Redirect Supply
Add your domain in Redirect Supply first. Its settings page shows the records you’ll need, including a TXT value that’s unique to your domain. Keep that page open in another tab. This guide covers a root domain like brand.cz. If you’re connecting a subdomain like go.brand.cz, the DNS setup guide explains the differences.
Check that Subreg runs your DNS
Subreg’s DNS zone only controls your domain when it uses Subreg’s nameservers. If your domain points to Cloudflare or another provider, add the records there instead. The Cloudflare DNS setup guide covers the most common case.
Open the DNS zone at Subreg
All the changes in this guide happen in one place.
Find the DNS zone
Sign in to the Subreg administration and open your list of domains. Select your domain and open its DNS zone settings. You’ll see every record in the zone and the option to add new ones.
Records you’ll see there
If the domain was parked, redirected through Subreg or connected to hosting, it already has records on the root domain and often on www. Those use the names Redirect Supply needs. Not sure what else counts? The conflict table on your domain’s page in Redirect Supply lists every record that blocks the setup.
Clear the way
Before adding anything, remove what’s already pointing your domain elsewhere.
Turn off Subreg redirection
Subreg offers free URL redirection for domains. If it’s turned on for this domain, switch it off first. It works through its own records and competes with Redirect Supply for the same names.
Remove old root and www records
Delete the A records on the root domain and any record on www. Remove any AAAA record on the root domain too, or visitors on IPv6 will keep reaching the old server.
Leave email records alone
MX records and email TXT records like SPF or DKIM keep your email working. They don’t affect redirects, so leave them exactly as they are.
Add the Redirect Supply records
You’ll add four records. Leave the name empty for the root domain, and enter only the prefix for anything else. Subreg adds your domain. Keep the default TTL.
Name | Type | Value |
|---|---|---|
www | CNAME | proxy.redirect.supply |
(leave empty) | A | 188.114.96.9 |
(leave empty) | A | 188.114.97.9 |
_cf-custom-hostname | TXT | Value from your domain’s settings page |
Add two A records for the root domain
Add an A record with an empty name and the value 188.114.96.9. Add a second A record with an empty name and the value 188.114.97.9.
Add the www CNAME
Add a CNAME record with the name www and the value proxy.redirect.supply.
Add the TXT record
Add a TXT record with the name _cf-custom-hostname and paste the value from your domain’s settings page in Redirect Supply. On some less common domain endings, Redirect Supply also asks for an _acme-challenge TXT record. Add it the same way if you see it. This rarely happens with .cz domains.
Save and check the zone
Save your changes, then look over the zone to make sure all four records are there and nothing else is left on the root domain or www.
Check the status in Redirect Supply
Once the zone is saved, you’re done in Subreg.
Check the conflict table
You don’t have to wait to find out if something’s wrong. Your domain’s page in Redirect Supply shows a conflict table with the records currently on your domain. Anything that blocks the setup, like a redirection record or a leftover www record, is flagged there along with what to do about it. Fix those first, and the rest is just waiting.
How long it takes
New records are usually picked up within an hour. If the old records had a long TTL, it can take a little longer before everyone sees the new ones.
When the domain goes Active
Redirect Supply checks your records automatically. When it finds them, the domain switches to Active and HTTPS is issued on its own, with no extra steps from you. See Domain statuses for what each status means along the way.
Subreg-specific issues
Most problems on Subreg come from redirection that’s still on.
The domain still redirects to the old place
Subreg’s URL redirection is still active. Turn it off for the domain, then check again in a private window, because browsers remember redirects.
Subreg won’t add the www CNAME
Another record already sits on www. Delete it first, then add the CNAME again.
Records have no effect
Your domain uses nameservers outside Subreg. Add the records with the provider your nameservers point to.
The domain is stuck on Pending
Open the conflict table on your domain’s page in Redirect Supply. It shows which record is blocking the setup, usually a redirection record or an old www record. Remove what it flags and wait a few minutes. Record conflicts covers the common cases.
