Which type of 'multi-homing' were you thinking about ?
http://en.wikipedia.org/wiki/Multihoming
* Single Link, Multiple IP address (Spaces)
* Multiple Interfaces, Single IP address per interface
* Multiple Links, Single IP address (Space)
* Multiple Links, Multiple IP address (Spaces)
Which type of 'cluster' were you thinking about ?
http://en.wikipedia.org/wiki/Computer_cluster
* High-availability (HA) clusters
* Load-balancing clusters
* Compute clusters
If any of these share the same IP address, they can share the same host
name.
I am not well acquainted with either of the above two methods,
multi-homed and clusters, but I can not understand why any of them
should resort to using fake identities when sending-out emails.
Can you help me understand why bogus identities are necessary in these
circumstances ?
Thank you.
