| 0x000E00C2 | This is similar to command 0x000D0082? |
| 0x000F0106 | This resolves the IP address(es) for the specified host-name. |
| 0x00110102 | getsockopt |

The socket descriptors are system-wide, they are not unique to each process.
struct sockaddr
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x1 | Total size of the entire sockaddr buffer. |
| 0x1 | 0x1 | u8 sa_family |
| 0x2 | sockaddr_totalsize-0x2 | sa_data[] |
The total buffer size is 0x8, for family AF_INET value 2. AF_INET6 seems to be value 23, the total sockaddr size for this is 0x1C. The max sockaddr buffer size which the socket module can handle is size 0x1C.
