Invalid IP

[bar3000]

Hi, I built an application using a TCP/IP connection. Therefore I need an I.P. checker to make sure the given IP is correct. I noticed that when an invalid IP is provided the complier can tell it right away. SO my quesion is if there is a command to check if an IP address is valid. By valid I mean it is less than 255.255.255.255. Or if you happen to have a code that does it i would be greatful. Thank you in advance :)

Hi, I haven't tried it myself but I would go for IPAddress.TryParse() :)

You could either ping it (requires internet access), use a regular expression, invoke the IPAddress.TryParse method or split it, and use Byte.TryParse on each of the components

Thanks, used IPAddress.TryParse() worked fine for me.
