Hello everyone. I am new to wireshark and i need help figuring some things out. i pinged www.mit.edu and i wrote down the details that appeared. Then i opened Wireshark, went to Analyze->Display Filters and chose IP ADDRESS option. Then i wrote on ''filter string'' section the ip adress that appeared when i pinged www.mit.edu Then i pinged www.mit.edu again and i saw on wireshark the source, destination, protocol used etc. Then i opened my browser and went to www.cnn.com. Then went back to cmd and pinged www.cnn.com but request timed out. My question is why my request timed out? Why i couldnt send packets at all? Thank you for spending time on reading this. I appreciate any kind of help :)

I guess there is a Firewall blocking your ICMP Echo Request packets. It allows HTTP of course, because otherwise you couldn't access their web site, but that is using TCP on port 80, not ICMP.
