If you prefer to run your own DNS infrastructure, you can use custom DNS servers with Stackryze Domains. This guide covers the requirements and a reference setup.
Stackryze Domains supports four namespaces — indevs.in, sryze.cc, ryzedns.org, and nx.kg. Examples below use yourname.indevs.in; substitute your registered namespace where applicable.

​
Requirements

Your custom DNS servers must meet these requirements:
  • Publicly accessible — reachable from the internet.
  • Authoritative — configured as authoritative for your subdomain.
  • Reliable — uptime above 99% recommended.
  • Standards compliant — follow DNS RFCs.
  • Multiple servers — at least two for redundancy.

​
Setup overview

​
Step 1 — Install DNS server software

Choose and install your preferred DNS server on your server(s).

​
Step 2 — Configure the zone

Create a zone file for your subdomain:

​
Step 3 — Test your configuration

Before registering, test your DNS servers:

​
Step 4 — Register with Stackryze Domains

Create your registration in the dashboard:
Then in the Stackryze Domains dashboard:
  1. Open My Domains → your domain → DNS Configuration.
  2. Replace the nameservers with your custom ones.
  3. Click Save.

​
Best practices

​
Use multiple nameservers

Always configure at least two nameservers for redundancy:
  • Primary: ns1.yourdomain.com
  • Secondary: ns2.yourdomain.com

​
Geographic distribution

Place nameservers in different geographic locations for reliability and performance.

​
Monitor uptime

Use monitoring tools to ensure your nameservers stay available:
  • UptimeRobot
  • Pingdom
  • StatusCake

​
Keep software updated

Update your DNS server regularly to patch vulnerabilities.

​
Enable DNSSEC (optional)

For stronger security, enable DNSSEC on your nameservers.

​
Common issues

​
Nameservers not responding

  • Check firewall rules (allow UDP/TCP 53).
  • Verify the DNS service is running.
  • Test with dig @your-nameserver-ip yourdomain.com.

​
Zone not loading

  • Check zone file syntax.
  • Review DNS server logs.
  • Verify the zone is loaded in configuration.

​
Slow DNS resolution

  • Optimize TTL values.
  • Enable DNS caching.
  • Check server resources (CPU, memory).

​
Security considerations

​
Restrict zone transfers

Only allow zone transfers to authorized secondaries:

​
Rate limiting

Implement rate limiting to prevent DNS amplification attacks.

​
Glue records

If your nameserver hostnames are under the same zone you’re delegating, set up glue records with your registrar.
