The two shortening rules
- Leading zeros in each group can be dropped:
0db8becomesdb8. - One run of all-zero groups can be replaced with
::, but only once per address.
The tool also tells you the address type, such as link-local (fe80::/10), unique local (fc00::/7) or the documentation range 2001:db8::/32.
