Question 1

What is the difference between IPv4 and IPv6?

Accepted Answer

IPv4 addresses use 32 bits and are written as four decimal numbers separated by dots (e.g., 192.168.1.1), allowing roughly 4.3 billion unique addresses. IPv6 uses 128 bits written as eight groups of four hexadecimal digits separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334), providing a virtually unlimited address space. Our generator creates valid-format addresses in both standards.

Question 2

What are private vs public IP addresses?

Accepted Answer

Private IP addresses are reserved for use within local networks and are not routable on the public internet. The private ranges are 10.0.0.0-10.255.255.255, 172.16.0.0-172.31.255.255, and 192.168.0.0-192.168.255.255. Public IP addresses are assigned by ISPs and are globally routable on the internet. Our generator lets you choose between private-only, public-only, or any range.

Question 3

Can I use these generated IPs for testing?

Accepted Answer

Yes, these randomly generated IP addresses are ideal for software testing, form validation, database seeding, network simulation, and development environments. They follow the correct format rules for IPv4 and IPv6 but are randomly generated and may or may not correspond to real allocated addresses.
