I am reading about ipv4 and I wonder how scientist determine the perfect size of packet for example here in RFC 791 said 512 B for payload + 64 B for ip-header
how they do that?
also what parameters they considered?
Another question is that why until now this is the same as that time?? how it still working properly, even today it get smaller!

I am not sure if this is the right platform to ask this question (does anyone of you know a community like this one where I can post questions solely related to Networking?), but can one AP have multiple bssid?
I checked the bssid of one particular AP, but it's bssid is showing different (does not match with its MAC that is there on company sticker it comes with).

I know in the ethernet header the destination address comes before the source address. Can you please explain me why is that ?
While this kind of questions is often futile (they had to pick one order; which one they choose might be random), there is indeed one very valid reason for this:
In order to work efficiently, the receiver wants to read the address of a packet very easy, perhaps even with the help of hardware (FPGA or ASIC).
And for this, it is handy to have this address at the very beginning.
