well good to know I don’t live to year 10k to see the next clock problem

I mean company is worth a few billion and last week at work they considered having a metal tool box to prop open the router room door “good enough”. I’m not in IT, but I was to walk in and write down the ip addresses and try to ping them from my workstation which just let open the command prompt. I literally said “WHY AM I ALLOWED TO DO THIS”

I remember my first class on NAT. The teacher said “this was not meant to be a security feature but that one use for it”.

we did a few tricks to get more use out of ipv4 address. take 192.168.100.1 that is a private ipv4 address it can not connect directly to the internet. Most home routers will have a single public ipv4 address and assign some private address to each device connected to it. So now each home can have 1 device with 192.168.100.1. This means we kept using ipv4 for a long time after ipv6 came out.

Second updating all the old routers and switches. At this point in time it is unlikely you will find a router in the wild that can’t use ipv6. Someone let me know the last time you found a device on some job site. But it took a while to get there because its expensive to replace them and no one was going to cough the massive amount of money to get it done in just a year or two.

Here is a full ipv6 address 2001:0db8:85a3:0000:0000:8a2e:0370:7334, yes it can be shortened to 2001:db8:85a3::8a2e:370:7334. That’s still a pain to type out and yes it did make a mistake just typing that one address. It is just more error prone to write and type out ipv6 addresses.

Its like the only accurate part of hackers
