Frequently asked questions
How is an IP address turned into a decimal number?
Treat each of the four octets as a base-256 digit: a times 16777216, plus b times 65536, plus c times 256, plus d.
How does IPv6 shortening work?
Leading zeros in each group are dropped, and one run of all-zero groups is replaced by a double colon. It can be used only once per address.
