So, my argument here is.... Why the hell are you memorizing IP addresses?
Is your DNS so misconfigured that you're still punching in IPs by hand?
DNS is the solution. Going to "router.domain.local" or whatever your internal domain is, is easier to remember than.... Which subnet am I on again? Is this one 192.168.22.254? Or 192.168.21.1?
Stop punching in numbers like a cave man. Use DNS. You won't even notice if it's IPv6 after that
