Folks:
I playing with Linux and wish know why World reportLocalAddress report 127.0.01 and ifconfig on Linux console gives me 192.168.1.4.
Hi Edgar, your system answer correctly, in Unix/Linux each network interface has an IP address. This is the ifconfig output on my Linux server:
[arrigo@aleph ~]$ /sbin/ifconfig eth0 Link encap:Ethernet HWaddr 00:0A:5E:05:9A:30 inet addr:192.168.1.200 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:3694 errors:0 dropped:0 overruns:0 frame:0 TX packets:3776 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:744868 (727.4 KiB) TX bytes:1465239 (1.3 MiB) Interrupt:19 Base address:0x8000

As you can see there are many eth interface with its IP address and at least the localhost 127.0.0.1. Maybe you have to change your request and ask for a specific interface.
Best Regards
