Which IPv6 address represents the most compressed form of the IPv6 address 2001:0db8:cafe:0000:0835:0000:0000:0aa0/80?
There are two rules that exist to help in the reduction of the number of digits within an IPv6 address:
Rule 1 is used to remove any leading 0s. After applying rule 1 to 2001:0db8:cafe:0000:0835:0000:0000:0aa0/80, we calculate the outcome as 2001:db8:cafe:0:835:0:0:aa0/80.
Rule 2 is used to replace any group of consecutive zeros once throughout the IPv6 address. After applying rule 2 to 2001:db8:cafe:0:835:0:0:aa0/80, we calculate the outcome as 2001:db8:cafe:0:835::aa0/80.
