IPv6 address shorthand

IPv6_address_shorthand.txt
8000/tcp -> [::]:8000 what does '[::]' mean?
The notation [::] is an IPv6 address shorthand representing the unspecified address, also known as "all zeroes" address. When you see 8000/tcp -> [::]:8000, it means that the service is listening on all IPv6 addresses ([::]) on port 8000.
Explanation
IPv6 Address: :: is the shorthand for the IPv6 address 0:0:0:0:0:0:0:0, which essentially means "listen on all available network interfaces".
Port: 8000 indicates the port number on which the service is listening.
In the context of your output:
8000/tcp indicates that the service is using TCP protocol on port 8000.
[::]:8000 means that the service is bound to port 8000 on all IPv6 addresses.
This is similar to 0.0.0.0 in IPv4, which means the service is listening on all IPv4 addresses.
