    Hello sir regarding your first question in this 3rd-day tutorial value of valid IP's are shown for 172.123.0.1-172.123.255.254 networks as it should be 133.123.0.1-133.123.255.254. Please correct me if I am wrong here.

    I have a doubt. When the IP address starts with 133.123. The valid address would be 133.123.0.1 to 133.123.255.254 . But in the video it is mentioned as 172.123

    at 26:27 mins, i got the answer right but how come Valip id address start is 172.123.0.1 to 172.123.255.254 since the IP address is 133.123.100.255 – so the valid IP address should start from 133.123.XX.XX since the network id is same?

    Please clear this confusion

    Hello Sir, i have been starting watching your videos and i feel they are amazing. I am very clear about IP add and Subnet but now i got some doubt about Gateway (i know this is a stupid question but cant wait to clarify), i guess many thinks in a classfull network if you put 1 in the last octant it is the gateway, is it true? i think out of valid IP's what ever the IP we assign to our Router/Firewall LAN interface will be the Gateway, right? i think i found the answer in my own question…….am i correct? Thank you Sir.

    at 26:17 your valid IP start and end addresses start with 172 in the first octet instead of 133. Other than that, great explanation.

    Thank you so much for making this series. May Allah reward you for it.
    I just had a question about the term Gateway. what will we be doing with the respective Gateway? what does it get used for? What does it do to the IP address?
    i hope i hear from you soon 🙂

    In minute 21:27 your calculation of the valid IPs is not correct. 2 to the power of 24 minus 2 is actually equal to 16,777,214 but yours is 2,097,150

    Just curious. I'm using my company laptop at my house and I'm connected to the company VPN.

    When I do an ipconfig, I get he IP of 10.144.XX.XXX (replaced actual numbers with X's in case this is some type of privacy breach)

    However, my gateway address is showing as 0.0.0.0

    Subnet is 255.255.255.255

    Question: If the IPv4 is supposed to be on the same network as the gateway, how are mine different, yet, I'm still able to connect to the network?

    SIr…
    1. Whether the gateway of my network is connected to the ISP?
    2. If two devices on the same network wants to communicate with each other, whether they will go to the gateway?
