I use command [status,result] = system('arp -a'), to get the IP address of my computer. there are lots of IP in the variable 'result', such as dynamic, staticstic, etc.
meanwhile, the result are also found to be different at different day. for example, using the same command, the variable 'result' is different between yesterday and today.
just want know what paramters in the 'result' is fixed in the machine, which will not changed with time?
Thanks!
Yu

What do you plan to do with this information? If we know your ultimate goal, we may be able to offer a way to achieve that goal without having to parse text returned by a system command.

Hi,
try:
[~, result] = system('ipconfig')
result:
Windows-IP-Konfiguration
Ethernet-Adapter LAN-Verbindung:
Verbindungsspezifisches DNS-Suffix: **.*********.de
IPv4-Adresse . . . . . . . . . . : **.***.**.**
Subnetzmaske . . . . . . . . . . : 255.255.255.0
Standardgateway . . . . . . . . . : **.***.**.*
for more detailed information use:
[~, result] = system('ipconfig -all')
The arp gives the adress Resolution protocoll - not your IP adress.

IPv4 address is not likely to be unique for your machine.
