About IP Address Generator
An IP (Internet Protocol) address is a unique numerical identifier assigned to each device on a network. Our generator creates random IP addresses in both IPv4 and IPv6 formats for testing and development purposes.
Common Use Cases
- Testing: Network application testing and debugging
- Development: Mock data for IP-based features
- Education: Learning about IP addressing and networking
- Simulation: Network simulation and modeling
- Documentation: Example IP addresses in technical docs
- Security Testing: Penetration testing and security audits
- Database Seeding: Populate test databases with IP data
IPv4 vs IPv6
| Feature | IPv4 | IPv6 |
|---|---|---|
| Address Length | 32 bits | 128 bits |
| Format | Decimal (dotted) | Hexadecimal (colon) |
| Total Addresses | 4.3 billion | 340 undecillion |
| Example | 192.168.0.1 | 2001:db8::1 |
| Adoption | Universal | Growing |
IPv4 Address Classes
| Class | Range | Default Mask | Purpose |
|---|---|---|---|
| A | 0.0.0.0 - 127.255.255.255 | 255.0.0.0 | Large networks |
| B | 128.0.0.0 - 191.255.255.255 | 255.255.0.0 | Medium networks |
| C | 192.0.0.0 - 223.255.255.255 | 255.255.255.0 | Small networks |
| D | 224.0.0.0 - 239.255.255.255 | N/A | Multicast |
| E | 240.0.0.0 - 255.255.255.255 | N/A | Experimental |
Private IP Address Ranges
These IP ranges are reserved for private networks and are not routable on the public internet:
- 10.0.0.0 - 10.255.255.255 (Class A private range)
- 172.16.0.0 - 172.31.255.255 (Class B private range)
- 192.168.0.0 - 192.168.255.255 (Class C private range)
- 127.0.0.0 - 127.255.255.255 (Loopback addresses)
Special IPv4 Addresses
- 0.0.0.0: Default route or unknown address
- 127.0.0.1: Localhost (loopback address)
- 255.255.255.255: Broadcast address
- 169.254.x.x: Link-local addresses (APIPA)
IPv6 Address Types
- Unicast: Identifies a single interface
- Multicast: Identifies multiple interfaces
- Anycast: Identifies nearest interface from a group
- Link-Local: fe80::/10 - Used within a single network segment
- Unique Local: fc00::/7 - Private addresses (like IPv4 private ranges)
- Global Unicast: 2000::/3 - Public internet addresses
Important Notes
- Generated IP addresses are random and may not be valid or assigned
- Use these addresses only for testing and development purposes
- Do not use generated IPs for actual network configuration without verification
- For documentation, use reserved ranges like 192.0.2.0/24 (TEST-NET-1)
- IPv6 addresses can be shortened by omitting leading zeros and consecutive zero groups
