How it works
We generate a valid IPv6 address, respecting syntax and enabling safe lab testing.
- Click Generate Random IPv6 to create a new address.
- Use the copy button to paste the address wherever needed.
- Repeat until you find a format that fits your scenario.
Practical examples
Some prefixes and common uses help set context:
2001:db8::1- Documentation range (2001:db8::/32): recommended for examples and manuals.fd12:3456:789a::42- ULA – Unique Local Address (fd00::/8): good for internal networks and labs.fe80::abcd:ef01:2345:6789- Link-local (fe80::/10): local autoconfiguration, not globally routable.
Tips and best practices
- Prefer ULA range addresses for internal labs.
- Avoid publishing production addresses in public tutorials.
- Document prefixes and subnets used in your tests.
- Pair with an appropriate prefix length (e.g.,
/64for LANs).
