[Winpcap-users] How can I get the IP addressofgatewaythroughWinPcap

Sun Jul 22 21:08:19 GMT 2007

Please refer to the Microsoft reference on the function:

http://msdn2.microsoft.com/en-us/library/aa365917.aspx

note, that the function returns an IP_ADAPTER_INFO structure defined at:

http://msdn2.microsoft.com/en-us/library/aa366062.aspx

note that IP_ADAPTER_INFO contains the gateway address.

		What he is saying is that you acknowledge that what you
are doing is not a good way of doing it.

		You could use the function GetAdaptersInfo which gives
you information about the adapter, all of it's IP address, and all of
it's gateway information. 

		Try that instead of this writing to a file kludge.

				thank you 
				but i used the windows command "ipconfig
/all " to obtaine the information of gateway
				then redirect the output to the file
				i get the info through reading this file
				although this is not a good way, i think
that this is a available one.

				Agreed. Also the ip of gateway can be
read from registry

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\I
nterfaces\{64B3C6C6-A3C4-4293-AC98-5BF7C17B467D}]\DefaultGateway 
				(DHCPDefaultGateway if dhcp enabled)
				{64B3C6C6-A3C4-4293-AC98-5BF7C17B467D}
can be get by parsing the
				device name of pcap_t. I was doing like
this because I don't want to
				download win platform sdk:-)
