Frequently Asked Questions

What is rst.st?

rst.st provides free subdomains for personal and non-commercial projects. You can register a subdomain like <code>yourname.rst.st</code> and use it for your website, blog, or testing.

How do I register?

Click "Register" in the top right corner, fill in your username, email, and password. If registration is open, you can sign up directly. If registration is invite-only, you'll need an invite code.

What record types are supported?

We support A, AAAA, CNAME, TXT, and NS records. You can manage them from your dashboard after logging in.

How many subdomains can I have?

Each user can create up to 10 different subdomains by default. For each subdomain, you can add up to 5 records per type (e.g., 5 A records for the same subdomain).

Domain validity period

No time limit, as long as it is used normally.

How do I add multiple NS records for the same subdomain?

Simply add them one by one from your dashboard. NS records are not subject to the 5-record limit, so you can add as many as you need for delegation, and they still only count as one subdomain toward your total.

How do invite codes work?

Users registered for at least 180 days can generate an invite code every 180 days. Codes are valid for 7 days and can be used by new users to register when open registration is disabled.

Can I use a custom domain?

No, this service only provides subdomains under rst.st. If you need a custom domain, you'll need to register it separately.

Is there any cost?

No, the service is completely free.

How do I report abuse?
