The valid IPv4 address format is d.d.d.d, where d is a decimal value from 0-255.
Valid IPv6 address formats are:
where d is a decimal value from 0-255 of an IPv4 address and x is a hexadecimal value of an IPv6 address.
A special syntax is available to compress long strings of zero bits. The use of '::' indicates multiple groups of zeros. The '::' can appear only once in an address. The '::' can also be used to compress the leading or trailing zeros in an address.
Specify a valid IP address, and resubmit the task.
