Okay,
I got ICMP to work. But heres the problem.

It doesnt work

I use the "GetLastError()" function, and I get error # 122, which i looked up
I think its 'bad address'

I checked my IP checking function, and i printed out what it returns. It looks fine.

Hostname www.vbworld.com resolved to 161.58.186.98
1656371873
Error: 122
Press any key to continue
now i think technically, if you enter the "1656371873" address into your browser, it'll bring you to VBWorld. It doesn't

My IP checking function is below that, and below that is the ICMP stuff.

Yahoo! comes out as a negative number.

Thanks guys

PHP Code:
