This guide walks you through claiming a subdomain under nxtdev.xyz and pointing it at a real host. The whole process takes under two minutes.

​
Prerequisites

  • A GitHub account — required for identity verification before you can claim
  • The host you want to point to (a Vercel deployment, a VPS IP address, etc.)
1

Sign up or sign in

Go to nxtdev.xyz and create an account or sign in. You can register with your email address or continue directly with GitHub.
2

Link your GitHub account

Before you can claim a subdomain, you must connect a GitHub account for identity verification. Open Settings in the dashboard and click Connect GitHub. You only need to do this once.
The claim form on the Domains page stays disabled until GitHub verification is complete. If you signed in with GitHub during registration, this step may already be done.
3

Claim a subdomain

Navigate to Dashboard > Domains. In the “Claim a subdomain” card, enter a base label — for example, alice — and submit the form. nxtdev.xyz registers alice.nxtdev.xyz under your account.Label rules:
  • 4–32 characters
  • Lowercase letters, digits, and hyphens only (a-z, 0-9, -)
  • Cannot start or end with a hyphen, or contain --
You can claim up to 2 subdomains on the free tier. The dashboard shows how many you have used next to the claim form.
4

Add a DNS record

Click Records next to your new subdomain to open the DNS editor. Add a record that points to your host.Use @ as the host name to target the apex (alice.nxtdev.xyz), or use a relative name like api to target api.alice.nxtdev.xyz.Vercel deployment (CNAME)
Type:   CNAME
Host:   @
Value:  cname.vercel-dns.com
TTL:    Auto
VPS or dedicated server (A record)
Type:   A
Host:   @
Value:  203.0.113.42
TTL:    60
Private IP ranges (10.x.x.x, 192.168.x.x, 172.16–31.x.x) are blocked on A and AAAA records. Use a public IP address.
5

Verify propagation

After saving the record, click Check propagation on the record row. nxtdev.xyz queries public resolvers and shows what they currently return for your record.Because the DNS infrastructure runs on Cloudflare, most records are visible globally within 60 seconds.

What’s next

Your subdomain is live. Here are a few things you can do from here:
  • Add more record types — MX for email, TXT for SPF/DKIM, SRV for game servers
  • Read DNS records for the full reference on each record type
  • Read Delegation if you want to point your own nameservers at your subdomain
