Random IP Generator
Generate random IPv4 and IPv6 addresses. Choose how many, pick private-range IPv4, and copy the list. Great test data for networking, apps and demos.
What is the Random IP Generator?
The ByteTools Random IP Generator creates random IPv4 and IPv6 addresses for testing, demos and sample data.
- Random IPv4 and IPv6 address generation
- Optional private-range IPv4 (10.x, 172.16–31.x, 192.168.x)
- Generate a single address or a large batch
- Correctly formatted, plausible-looking output
- Cryptographically secure randomness
- Copy the list — everything runs in your browser
How to use the Random IP Generator
- 1
Choose IPv4, IPv6, or both.
- 2
For IPv4, tick "Private ranges only" if you want internal-style addresses.
- 3
Set how many addresses to generate.
- 4
Click Generate to build the list.
- 5
Copy the addresses for use in your tests or docs.
About the Random IP Generator
The ByteTools Random IP Generator creates random IPv4 and IPv6 addresses for testing, demos and sample data. Choose the version you need, decide how many addresses to generate, and copy the whole list — with a switch to keep IPv4 addresses inside the private ranges used on home and office networks.
It is handy for developers and QA engineers seeding databases and log files, network trainers building example scenarios, and anyone who needs plausible-looking addresses without using real ones. Private-range mode produces 10.x, 172.16–31.x and 192.168.x addresses so nothing points at real public hosts.
Every address is generated locally in your browser using a cryptographically secure random source. No data is uploaded or stored, so you can create as many random IPs as you like, instantly and privately.
Frequently asked questions
What is the difference between IPv4 and IPv6?
IPv4 addresses are 32-bit and written as four numbers like 203.0.113.5, while IPv6 addresses are 128-bit and written as eight hex groups like 2001:db8::1. IPv6 exists because the world ran out of unique IPv4 addresses.
What are private IP address ranges?
Private ranges are reserved for internal networks and never routed on the public internet: 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16 for IPv4. Turn on private-range mode to generate addresses only from these blocks.
Can I use these random IPs as test data?
Yes, that is their main purpose — seeding databases, log files, firewall rules and demos. For documentation, the reserved ranges (like 192.0.2.0/24) or private ranges avoid any risk of matching a real live host.
Are the generated IP addresses real or assigned to anyone?
They are random values in valid formats and may coincidentally match an address that is in use somewhere. For that reason, treat them as sample data only and avoid sending traffic to random public addresses you generate.
How many IP addresses can I generate at once?
You can generate a whole batch in a single click. Because everything runs locally in your browser, it stays fast even for large lists, and nothing about the addresses is uploaded or logged.
