Your destination,
with a name.

Turn any public or private IP address into an easy-to-use hostname. Just add .dst.is.

How it works

dst.is turns an IP address into a hostname that points back to it.

  1. 01
    Enter an IP address
    Use a public or private IPv4 address.
  2. 02
    Add an optional prefix
    Give the hostname a memorable name if you want one.
  3. 03
    Use the hostname
    Use the generated hostname anywhere you would normally use a DNS name. 
10.0.0.1
      ↓
10.0.0.1.dst.is
      ↓
10.0.0.1

Use the format you need.

Keep it simple, or add a name when you need one.

  • 10.0.0.1.dst.is
    Simple IP-based hostname.
  • app.10.0.0.1.dst.is
    With a name.
  • 10-0-0-1.dst.is
    Use hyphens instead of dots.
  • app-10-0-0-1.dst.is
    With a name and a hyphenated IP.

Works with your local network, too.

Private IP addresses work just like public ones when the network can reach them.

  • 10.0.0.1.dst.is — A hostname for a private network address.
  • 192.168.1.20.dst.is — Useful for devices and services on your LAN.
  • 172.16.0.10.dst.is — Another common private address range.
Private IP addresses are only reachable from networks that can reach those addresses. dst.is provides the hostname; it does not make a private network publicly accessible.

Simple by design.

  • Nothing to configure — No DNS records to create or maintain.
  • No account — Just use the service.
  • Easy to remember — The IP address is part of the hostname.
  • Useful anywhere — Use the hostname wherever you would normally use a DNS name.

Examples

# Simple
$ curl http://10.0.0.1.dst.is

# With a name
$ curl http://app.10.0.0.1.dst.is

# Hyphenated format
$ curl http://app-10-0-0-1.dst.is

# In a URL
https://192.168.1.20.dst.is/

FAQ

What is dst.is?

dst.is turns IPv4 addresses into hostnames. Instead of using an IP address directly, you can use a hostname based on that address.

Can I use private IP addresses?

Yes. Private IPv4 addresses such as 10.0.0.1, 192.168.1.20, and 172.16.0.10 can be used.

Does dst.is make my local server accessible from the internet?

No. A private IP address is still only reachable from networks that can reach that address. dst.is provides the hostname; it does not create a tunnel or expose your network.

Do I need to configure DNS?

No DNS records need to be created manually. Just use the hostname generated by dst.is.

How do I report abuse?

If you see dst.is being used for abuse, please report it to abuse@dst.is. We review abuse reports and take appropriate action.
