I understand that computer names are somewhat arbitrary. I know a group that named their computers after the seven dwarfs. I tend to name my by the brand/model of the machine since it is rare that I ever have two alike. My two most recent machines were built by ENU (R.I.P). I named them ENU-1 and ENU-2. When I installed Ubuntu MATE 18.04 on the box I call ENU-1 I tried to use that name. The complaint was that there was already a computer on the network with that name, so for the time being I named it ENU-1.1.

Two questions.

1. How did the install process know there was a computer named ENU-1, if ENU-1 wasn't there? Did it find it through a table in the router?

2. If I change that table will everybody be happy? (I have a list of computers in the router so that they always get assigned the same IP address.)

Thanks.
