    Every day I regret becoming a network engineer more and more

    You have a clusterfuck of a clusterfuck because corpocunts make more money from keeping everyone on shit old stacks

    The network engineer to communist/anarchist pipeline is real

    I would love a horror game set in a massive building with nothing but networking equipment. With the goal being to fix and patch old parts of the system finding more and more awful things that have happened to the previous employees.

    Funny how many here took this to be real, judging from the reactions. To me it’s an obvious joke.

    Question to you guys: How do you suppose 200 million customers will share the less than 65’536 ports that are available on that one address?

    I know this is humor, but for the record this wouldn’t work. Each simultaneous TCP connection needs a unique four-tuple (source address, source port, destination address, destination port). If a lot the people behind the NAT try to connect to the same place (destination address and port) at the same time (something popular like Google, YouTube or Netflix), and their source address is the same, the source port needs to be different for each connection. So after at most 65535 connections within a short time the NAT would run out of ports and no one behind the same NAT would be able to open new connections to the same place until the NAT mapping expiries.

    So you could have at most tens of thousands of people behind the same NAT, maybe even fewer to make it reliable.

      Don’t forget the tech giants are all IPv6 enabled. Google Netflix Apple xhamster Facebook Microsoft are all reachable over v6.

        OK, bad examples. On the other hand e.g. X, GitHub, Pornhub, PSN, Steam or Discord do not support IPv6.
