If you are using dhcp, you can simply move to another country and plug  
your computer in… voila … new ip!

As for changing the mac address, you can always buy a new nic… (If it  
will be hard to acquire it in the new country you move to, make sure to  
buy one before you leave)

¿¿from source code ruby?? 😑

well ,  
if you use un debian distro, from console this are steps

1. #: apt-get install lshw  
#: lshw | less

\*-network  
description: Ethernet interface  
product: 88E8053 PCI-E Gigabit Ethernet Controller  
vendor: Marvell Technology Group Ltd.  
physical id: 0  
bus info: pci@0000:03:00.0

> > > > > > > > logical name: eth0\<\<\<\<\<\<\<\<\<\<

if is “eth0” your netcard then

1. #: macchanger --mac “00:5D:6E:4D:5W:4B” eth0

where “00:5D:6E:4D:5W:4B” is the new mac address

and then

1. you going to edit “/etc/network/interfaces”

iface eth0 inet static  
address “10.1.1.15” ##====\> “YOUR NEW IP ADDRESS”  
netmask “255.255.255.0”  
network “10.1.1.0”  
broadcast 10.1.1.255  
gateway 192.168.1.2

maybe this question is apropiate for other list of distros linux if  
you not want do this from source code Ruby. I don’t write english very  
well, sorry!! i hope you understand my explanation. bye
