What's the minimum length of an IP address in string representation?

Question

Just wondering about the minimum character count of an IPv4 / IPv6 address in string representation. What's the shortest valid IP address?

Answer 1

1.1.1.1 would be a valid IP address, so the answer to your question is "7".

Answer 2

Technically, you can omit the first three octects if the are 0, therefore shortest ipv4 address is one byte, it is "1", a shorthand for "0.0.0.1".
