[ale] sendmail -mindspring-ISP ignorance

[Chris Fowler]

Many times I've placed the IP addresses in /etc/hosts to save time on V.90.  You are both correct.  If the SA relies on DNS and changes the IP of the server, that is okay as long as DNS is updated.  If the users has the old IP Address in /etc/hosts, they will not make a connection.   In the end, DNS names should be used, not IPs.

I find nothing stupid in that.  I was under the impression that DNS
was for this type of scenario exactly.  Names may never need change
but IP's OTOH may change frequently.


Being an SA I have done this many times and it still baffles me how
people complain about IP's changing although the DNS entry has always
pointed correctly.


MHO only.  :)
