In video Full Stack Analysis with Wireshark of PTS prerequisites, I have one doubt.
At time 3:03-3:10, I can hear like Presenter is saying 10.11.12.145 and 10.100.13.37 aren’t two different networks.
From my understanding If you are sending a packet to another host in same LAN, destination MAC address is
MAC address of host. From Packet number 5 it is certain that MAC address in destination is the router’s.
It is same MAC address used in so that means either 10.100.13.37 is the router’s IP address or the IP is in different LAN,
then only destination MAC address should be the router’s right?.
But from the ARP request we can see that same MAC address is returned by 10.11.12.4 not 10.100.13.37.
So In that case it is the second one that is the IP is in different LAN.
But in the video I heard it like “aren’t two different network”.
Maybe what I understood can be wrong.
