i love my hilariously memorable ipv4
Jak jsem se pak divil, když ze všech zařízení začaly mizet IPv4 adresy a hromada věcí přestala fungovat (zatímco druhá hromada, co jede po IPv6), jela úplně krásně.

The Port That Does Not Exist

Port 0 is the port you are not supposed to use, so nobody looks there. So… then I got curious whether anyone else had, & scanned all of IPv4 for port 0. Turns out we weren't alone, & some of our neighbours really shouldn't be there.

I have been wondering for a while if genAI will finally, via side-effect, manage to give IPv6 adoption a significant push.
CGNAT (Carrier-Grade Network Address Translation) has been an effective workaround for IPv4 address space exhaustion for 15+ years but Muse and friends might see an end to it.

An IPv4 address is a unique numerical identifier that helps devices communicate over the internet and local networks
Every time you browse a website, send an email,or stream a video your device uses an IP address to exchange information .An IPv4 address contains four separate numbers called octets.
