I stopped manually entering Network information 12 years ago.
I set up new PC’s at work (for our dept) Our company network established a DHCP server, at least by 2002. I was finally told to use it and stop entering the Network information manually around 2004 or 05. I really preferred using static IP’s. But, I’m just a worker bee. I do what I is told.
At home, I’ve used DHCP even longer. Certainly since getting DSL in 1998.
