strang IPv6 addresses - what do they translate to?

Posted on 2011-10-27

I'm looking at a listing of information that shows IP addresses and port numbers for several services running on a machine.  Most of them look like normal IPv4 addresses, but some of the other ones look rather strange.  I asked a buddy what they were and he said they were probably some IPv6 shorthand addresses.

[::] - he said this one was a loop back address (correct?)
[::1] - he didn't know what this was
*:* - he didn't know what this was either

As I'm importing this information into a database and it won't go into the current schema, I need to know what the replacement IPv4 addresses would look like.

    Accepted Solution

    :: is the unspecified address - it means any IPv6 address
    ::1 is the IPv6 loopback address
    *.* isn't any type of standard address. Using traditional DOS wildcards, this might indicate any IPv4 address, or any of 'some type' of address. But this isn't traditional IPv6 notation.
