Random IP Guide: How Dotted-Quad Addresses Are Built
Learn the four-number structure of an IPv4 address and why random ones are only examples.
What is the Random IP Generator?
Choose how many addresses you need and this tool builds each one from four random numbers between 0 and 255, joined by dots. The results are random examples for testing, documentation and placeholders. They are not checked against any assignment list, so a generated address may coincide with a real one by chance and must not be treated as owned or safe.
How to use it
- Set how many addresses you need.
- Click Generate.
- Copy the dotted-quad addresses into your test or example.
Worked example
For the sample count of 1, the tool returns a single address in dotted-quad format, four numbers from 0 to 255 separated by dots; the exact address varies on each run.
What does each number in an IPv4 address mean?
Each of the four parts is an 8-bit number from 0 to 255, and together they form the 32-bit address that identifies a device on an IPv4 network.
Frequently asked questions
Are the generated addresses guaranteed unused?
No. They are random numbers in the IPv4 range and may match a real address by chance, so do not treat them as free or safe.
Can it generate IPv6 addresses?
No. This tool only makes IPv4 dotted-quad addresses.
