There must be a function out in builder that will tell you what your computer ip address is.

There is nothing in Builder itself for that.  You have to go to the Win32
API for it.  You have two choices:

1) gethostname() and gethostbyname().  Look in the h_addr_list member of the
hostent structure that gethostbyname() returns.

2) GetAdaptersInfo().  Look at the IpAddressList member of the
IP_ADAPTER_INFO structure that it returns.

Note, however, that these can only return the IP address(es) that are
assigned directly to the machine.  If your machine is on a network, and the
Internet address is assigned to a router or to another machine that has
Internet Connection Sharing enabled, then you will not be able to obtain the
Internet IP address directly.  You will have to query an external server,
such as by sending an HTTP request to http://iplookup.flashfxp.com.
