The two things are entirely independent.  It is not true that there
is any relationship between name service and the number of IP addresses
on a single host, and it is absolutely not true that it is common for
a host to have multiple IP addresses.  Unless, of course, your definition
of "common" is radically different.

Again, this is independent of the mechanism used for hostname lookup.
In the musty, dusty days before name service I had to fix the routing
code in a hyperchannel driver for just this reason.
