Deeply deeply agree with you. Not whoever was arguing. :) My "dialup" VM in the cloud I use for assorted things has had the same IP for at least 7 years, probably longer. (Thanks Linode!) After a few years, it's honestly not that hard to remember an arbitrary 32bit int. :)

Obviously a server vm getting renumbered is a rare occurance.
