[gpfsug-discuss] Weirdness with 'mmces address add'

[Stephen Ulmer]

Hostnames can have many A records. IPs *generally* only have one PTR (though it’s not restricted, multiple PTRs is not recommended). Just knowing that you can see why allowing names would create more questions than it answers.

So if it did take names instead of IP addresses, it would usually only do what you meant part of the time -- and sometimes none of the time. :)
