Specifically, if you have a set of well known IP addresses for common services, thus something like: 223.255.255.1 - Primary DNS 223.255.255.2 - Secondary DNS 223.255.255.3 - SMTP Mail 223.255.255.4 - Time ServerWhy did you choose to have exactly 2 DNS servers and exactly 1 SMTP and "time" server?
This seems a big drawback to the standard IP number method. Think about a network sharing an IGP containing thousands of dialup ports. That's where I am. How many dialup ports can you have before one SMTP gateway just doesn't cut it? Sure you can play games with load balancing, layer 4 switches, or perhaps route filtering but why force money or effort to be wasted on such things? ---------------------------------------------------------------------- Jon Lewis *jlewis () lewis org*| Spammers will be winnuked or System Administrator | nestea'd...whatever it takes Atlantic Net | to get the job done. _________http://www.lewis.org/~jlewis/pgp for PGP public key__________
