Xip.nz Free DNS Service without the DNS Setup

A free public DNS service from BTIT

xip.nz

Put an IP address in a hostname.
Get that IP address back from DNS.

xip.nz is a simple wildcard DNS service for developers, sysadmins, homelabbers and anyone who needs a hostname for an IP address without creating DNS records first.

DNS without the DNS setup

When you're building a lab, testing an application or deploying a temporary service, creating a DNS zone and adding records can be unnecessary overhead.

xip.nz makes the hostname itself the DNS record.

Include an IPv4 address in a hostname under xip.nz and the service returns that address when the name is resolved.

How it works

There's nothing to register, configure or provision.

1

Take your IP address

For example: 160.30.240.36

2

Add xip.nz

Use: 160.30.240.36.xip.nz

3

DNS resolves it

The hostname resolves back to: 160.30.240.36

Use meaningful hostnames too

The IP address can be part of a longer hostname, making xip.nz useful for applications that require host-based routing, TLS certificates or virtual hosts.

Basic
160.30.240.36.xip.nz

Resolves to 160.30.240.36.

Application
app.160.30.240.36.xip.nz

Resolves to the same IP with a useful application hostname.

Development
dev.192.168.114.42.xip.nz

Useful inside a network, development environment or homelab.

Multiple services
grafana.192.168.114.42.xip.nz

Give different applications meaningful names while pointing them at the same host.

Made for building things

xip.nz is especially useful where conventional DNS administration would add friction without adding much value.

πŸ§ͺ

Development

Give development applications real hostnames without creating temporary DNS records.

🏠

Homelabs

Use friendly hostnames for services running on private network addresses.

πŸ“¦

Containers

Quickly test reverse proxies, container platforms and host-based routing.

☸️

Kubernetes

Create useful temporary hostnames for ingress controllers and test clusters.

πŸ”§

Infrastructure testing

Test applications before permanent production DNS records have been created.

πŸš€

Proofs of concept

Get prototypes and demonstrations running quickly without involving DNS administration.

🌐 xip.nz is DNS

xip.nz provides name resolution only.

Your web, SSH, application or other traffic goes directly between your client and the IP address encoded in the hostname.

xip.nz is not a proxy, VPN or traffic relay.

πŸ”’ Private addresses are still private

A hostname resolving to an RFC1918 address such as 192.168.1.20 does not make that system accessible from the Internet.

Normal routing, firewall and network security rules continue to apply.

Why does BTIT run this?

Because useful infrastructure doesn't always need an account, subscription or billing relationship.

BTIT relies heavily on open-source software and the communities that build and maintain it. We believe organisations that benefit from that ecosystem should contribute something back.

xip.nz is one of those contributions.

We operate it as a free public service for developers, engineers, students, homelabbers and anyone else who finds it useful.

Built and operated in New Zealand by BTIT .

Please use xip.nz responsibly. The service is intended for legitimate development, testing, infrastructure and application use. Availability is provided on a best-effort basis and should not be treated as a replacement for authoritative DNS for critical production systems.
