get computer IP problem
显示 更早的评论
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!

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.

Another way to get the MAC adress easily:
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]);

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.
