Frequently asked questions
What is an IP address as a decimal number?
An IPv4 address is four bytes, so it is also one 32-bit number. 192.168.0.1 is 3232235521. Some tools and databases store addresses this way.
Which addresses are private?
10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16 are private. 100.64.0.0/10 is carrier-grade NAT. 127.0.0.0/8 is loopback and 169.254.0.0/16 is link-local.
What is an IPv4-mapped IPv6 address?
It is an IPv4 address written inside an IPv6 address, as ::ffff:192.168.0.1. It lets IPv6 software handle IPv4 clients.
Is anything uploaded?
