It seems my router foo is not strong enough. Routeros 6 newest. Groove newest. Device not connecting Splat SX10509 - RS485 to Ethernet converter running a wiznet W5100 with some custom config that we have no access to. 3691053495 is mac address in decimal. Ubiquity Bullet works with the device. Hoping to move to Groove if we can get this problem solved. Attached the log file with dhcp out put enabled and

. Some help please.
A little wire sharking on the ubiquity device revealed initial arp is wiznet_01:0:B7 then id369105495.local. I am guessing the dot local is an MS addition. I hope that helps.
Is that a function of dnsmasq?
More likely an mDNS implementation in accord with RFC6762.
That then raises two new matters:
- If your problem is with mDNS, asking here goes quickly off-topic. RouterOS doesn’t currently offer an mDNS server. You’d be better off chasing this on the mDNS provider’s forums since RouterOS’s DHCP features plainly aren’t dominating in your network, for this device at least.
- If the problem is with this mystery mDNS provider fighting with dnsmasq, that is even more irrelevant here, since the only way dnsmasq is running on your RouterOS device is if it’s inside a container, and if that’s the case, your question is poorly-asked and not in the right sub-forum to begin with.
@tangent Thanks for the mDNS point and I agree it is most likely an mDNS Issue. So my question is, since this device is the only device on the LAN side of the groove and has to be in router mode because it will only take a 192.168 address, is there a work around that someone knows that I don’t? Like creating multiple static arp maps to a specific ip? So router 1.1 and dhcp range 1.2-1.3 and configure them just for the device and a static for the laptop if it needs to connect to the device on a dumb switch.
