Briefly, it is referred to as "Zero Configuration Networking". I say it could clarify the distinction as a result of I do know little or no about Home windows, so that is extra hypothesis, reasonably than a solution based mostly on direct information.
That mentioned, I recall listening to/studying that Home windows didn't help "Zero Configuration Networking" out-of-the-box - it required the addition of some software program (Apple's
Bonjour possibly?). Maybe it is the case that your older Win 8 would not help ZCN, however the newer Win 10 does? Strive an Web search to get additional particulars.
I additionally suspect that @rtaft's remark/suggestion could resolve your situation - however maybe on the expense of making one other situation! What am I speaking about? We get numerous questions right here from individuals who try to arrange a hard and fast IP tackle, however bungle it as a result of they fail to learn the documentation (
man dhcpcd and
man dhcpcd-conf). Please do not make that mistake; there's very seldom a sound reason for setting up a fixed IP, however when you do it, please learn the docs & do it appropriately.
