Joe pointed out a subtle thing about TCPGetMyAddr.  You get different results in different situations.  If you use a socket that's created but not connected to anything, you'll get 0.0.0.0.  If you use a socket that's connected to a server like Joe illustrated, you'll get the proper LAN address of the machine hosting Omnis. (10.0.0.11 in my case)

With TCPName2Addr it's emulating a DNS lookup.  When passed the 'sharing name' of the machine, it will give you an APIPA self-assigned IP 169.254.xxx.  When passed an unrecognized name, it returns a simple 0.  When passed a dotted IP address, it returns the same dotted IP.

-------------------------------------------------  (tested with Studio 10.22 and 11.1 on a Mac)
    TCPSocket Returns sock
    TCPGetMyAddr (sock,kFalse) Returns addr1
    TCPClose (sock,0)

    TCPConnect ('www.google.com',80) Returns sock
    TCPGetMyAddr (sock,kFalse) Returns addr2
    TCPClose (sock,0)

    TCPName2Addr ('localhost') Returns addr3
    TCPName2Addr ('MacPro.local') Returns addr4
    TCPName2Addr ('www.google.com') Returns addr5

    Breakpoint [addr1] -- [addr2] -- [addr3] -- [addr4] -- [addr5]

0.0.0.0 -- 10.0.0.11 -- 127.0.0.1 -- 169.254.121.115 -- 142.251.215.228

My TCPTools xcomp has the $interfacelist() method that Doug described. (I've also put that function in my UniqueID xcomp.)  TCPTools is a collection of some old TCPTalk utility commands that got ported to an xcomp.  TCPTalk itself never made it to 64bits, because by that time, Omnis had those bases covered for the most part.

    Calculate iInterfaceList as TCPTools.$interfacelist()
    Do iInterfaceList.$sort($ref.type,kFalse,$ref.name,kFalse)

  type           address                          name

It's worth pointing out that Joe mentioned looking for an IP matching the en0 interface obtained from some other script, and that *could* be a problem, as illustrated above.  I've got a MacPro that has two ethernet connectors, and I just happened to plug the cable into the one for en1, leaving en0 unconnected, so this machine has ethernet connected but en0 ain't it... so, word of caution there.
