Is the subdomain really free?
Yes. There is no account, no payment method and no trial. You choose a name, add a target, and the record is written straight into the zone.
Free subdomain service
A free subdomain on shahzaibnagi.dev
Choose a name and point it at your server, VPS or hosting provider. Records are written to the zone immediately and resolve within a few minutes.
Useful for staging environments, portfolio demos, bots, APIs and side projects that don't justify buying a domain.
How it works
1
Pick a name
Names are checked against the live zone as you type, so you know immediately whether one is available.
2
Add your target
Enter an IPv4 address, IPv6 address, or a hostname if you are using CNAME with a hosting provider.
3
Point DNS at it
The record is created with a 300 second TTL. Most resolvers pick it up within one to five minutes.
Record types
| Type | Use it for | Value format |
|---|---|---|
| A | Servers with a fixed IPv4 address (VPS, dedicated host, bare metal). | 203.0.113.10 |
| AAAA | Hosts reachable over IPv6 only, or dual-stack servers. | 2001:db8::1 |
| CNAME | Platforms that give you a hostname instead of an IP, such as Vercel, Netlify or Railway. | app.vercel.app |
Frequently asked questions
Which DNS record types can I create?
A records for IPv4 addresses, AAAA records for IPv6 addresses, and CNAME records for hostnames such as app.vercel.app. All records are created with a 300 second TTL.
How long does a new subdomain take to go live?
The record is published immediately. Most public resolvers pick it up within one to five minutes, limited mainly by their cache.
Can I use this subdomain with Vercel, Netlify or Railway?
Yes. Choose CNAME as the record type and enter the hostname the platform gives you. Those platforms then issue their own TLS certificate for the subdomain.
Do you provide an SSL certificate?
No. This service publishes DNS records only. TLS is issued by whoever hosts your site; Let's Encrypt is free and automatic on most platforms.
Can I delete a subdomain later?
Yes. Delete it from the same page you created it on. The DNS record is removed and the name becomes available again straight away.
Are there any limits?
Six new subdomains per hour per IP address, twenty active subdomains per IP address, and a daily service-wide cap. Reserved names such as www, mail, api and admin cannot be registered.
