> Because I kept reading about why DNS was created and always encountered the same parroted explanation, year after year. Something along the lines that IP addresses were constantly in flux. That may have been true when DNS was created and the www was young. But was it true today. I wanted to find out. I did experiments. I found I could use the same DNS data day after day, week after week, month after month, year after year.
I have never in my life heard anyone claim this as the reason for dns.
The usual reason given is two fold:
Flat /etc/hosts files were getting large enough to be annoying.
The set of all dns records as a whole change constantly. Individual records dont change very much. But the time between at least one record changing is very small.
Both of these things are even more true today then they were when dns was invented.
