Uplne jednoducho:
* V Linuxe, NetworkManager s dns=dnsmasq umoznuje mat DNS pre kazdy interface a zadefinovat, ktore domeny sa cez neho maju resolvovat
* Pod macOS, to iste umoznuje aj resolver na macOS, pomocou /etc/resolver/*, resp. scutil.
* Pod Windows to umoznuje NPRT (Name Resolution Policy Table) - Add-DnsClientNrptRule -Namespace "intranet.domena.cz" -NameServers "10.0.0.1" a priradenim prislusnych DNS na prislusnych interace.
Takze vas problem nie je limit DNS, ale problem vasej konfiguracie.
