Beacuse i would like to catch all types of ipv6 formats

ex:
Code:
2001:0db8:0000:0000:0000:0000:1428:07ab/64
 2001:0db8:0000:0000:0000::1428:07ab/64
2001:0db8:0:0:0:0:1428:07ab/64
2001:0db8:0::0:1428:07ab/64 
2001:0db8::1428:07ab/64
2001:db8::1428:7ab/64

OK, so how about
Code:
IPV6CHECK="([[:xdigit:]]*:){4,7}[[:xdigit:]]{1,3}(\/[[:digit:]]{1,2})*"
