I'm working on adding some new troubleshooting code to a product, and discovered the "getpeername()" call in the socket section of the "unix-type API" manual.

I've called it successfully, but I'm not entirely sure what I'm getting

The first two bytes are 00 02; that seems to fit with the first two bytes being the "address family," and family 2 being Internet.

Then I get DA 31 C0 A8 01 0F. Now the internal IP address of the Mac I connected from in the test is 192.168.1.15, which accounts for the C0 A8 01 0F,
but where is the DA 31 coming from? All of the docs talk about IPv6 addresses, but a complete 128-bit IPv6 address would take up more bytes than the sockaddr structure provides.

Does anybody here know enough about what's going on to shed any light on this?
