Is this a machine name or what?

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开发者_Python百科 \192.168.1.120 and get happy???

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.

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

The 3rd option is a IPv6 address
