Hi,
I am trying to make a setup where hosts on the LAN, configured using DHCP can be looked up using the hostname.
I have similar setups on other brands, such as Ubiquiti USG, Edgerouter and Asuswrt, all based on dnsmasq, where it is straight forward to setup.
On these systems I can specify a domain name for the LAN. When a host get a DHCP lease, the router creates a DNS entry in the form [host name].xxx.yyy.zz, where xxx.yyy.zz is the domain I have specified. This allows me to reach all my hosts using a FQDN based on their hostname.
Meanwhile it seems that Routeros does not do this, even if I specify a domain in dhcp settings.
I have tried doing dns lookups on my local router which returns nothing, and simliarly doing reverse dns lookups on IP addresses assigned to hosts in the network, similarly with no results.
I have seen other post suggesting using static IP addresses, and adding static DNS entries for each host, but it seems like a lot of bookkeeping for something that is running automatically on other systems.
If anyone has this working I would be very thankful for a hint! 
Bset regards,
Crilles
