Close, you need 8 sets of hex numbers in each group of four, but basically, you got the idea. 1000.0000.0000.0000.0000.0000.0000.0001 drops down to 1000::1. Remember that the double colons represent the 0000 only, and you can't drop trailing zeros, only leading zeroes. (You have to keep the 1000 but can drop the zeroes in 0001.)
"Flyingmonkie: The short of IPv6 is this. You can replace a continuous stream of zero's with to colons ( :: ) however you can only do this once (If there is a single digit other than a zero in the group of 8, you can't do this). You can also drop leading zeros. So, 0000.0000.0000.0000.0000.0000.0000.0001 becomes ::1 (or as we write it ::1/128)."
so now another question lets say its 1000.0000.0000.0001 or something like that can i drop the the zeros to 1::1? or did i get that wrong?
