Is this a machine name or what?

Question

I have a third party dll, that is supposed to return machine name. Sometimes it returns

\\John-PC

some other times it returns

\\192.168.1.120

and recently i discovered that it returns something like this

\\[ef80::32d6:2255:27dd:123c]

So what is the third option?

If it is not a bug or MAC orelse, could i convert it to \192.168.1.120 and get happy???

Answer 1

It is the IPv6 version of the IPv4 address 192.168.1.120 . It also amuses me how your DLL seems to be indecisive with what to return.

Answer 2

The 3rd option is a IPv6 address

Answer 3

It's an IPv6 address. IPv6 allows you to leave out sections that are equal to 0, hence the ::.
