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.

01

Enter an IP address

Use a public or private IPv4 address.
02

Add an optional prefix

Give the hostname a memorable name if you want one.
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.
