how to extract ipv6 addresses from a file












1















I want to grep ipv6 addresses in below format
like 2a01:1388:120:720::1000 and 2b00:1188:210:9::2005



i use this to grep ipv4’s from a file



1.egrep '[[:digit:]]{1,3}.[[:digit:]]{1,3}.[[:digit:]]{1,3}.[[:digit:]]{1,3}' file



2.grep -E -o '(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)' file



Omit the -o if you want to see the entire line that matched.



Is there any similar regex for ipv6?






ipv6
