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

Ran in:
using following matlab code to get computer IP address
% Use Java's InetAddress class to get the local host
host = java.net.InetAddress.getLocalHost();
% Get the IP address as a string
ipAddress = char(host.getHostAddress());
% Display the IP address
disp(['Local IP Address: ', ipAddress]);
Local IP Address: 10.168.118.61

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.
