Local DNS not working. NanoPi R4S

Hello,
I have a NanoPi R4S running openwrt fork "immortalWRT" as an official release isn't out yet. When I first got it up and running, I was able to use hostname/ to get to the router. I changed the IP scheme from 192.168.2.* to 10.10.10.* and now it doesn't work. I can't connect to any local devices via hostname. Under DHCP options I have it set to /lan/ and "lan" .. but nothing is working. I have tried hostname.lan/ and hostname/.

I don't really know where to start other than reinstalling and sticking with 192.168.2.*.
Here is my dnsmasq config

dhcp.cfg01411c=dnsmasq
dhcp.cfg01411c.domainneeded='1'
dhcp.cfg01411c.localise_queries='1'
dhcp.cfg01411c.rebind_protection='1'
dhcp.cfg01411c.rebind_localhost='1'
dhcp.cfg01411c.local='/lan/'
dhcp.cfg01411c.domain='lan'
dhcp.cfg01411c.expandhosts='1'
dhcp.cfg01411c.authoritative='1'
dhcp.cfg01411c.readethers='1'
dhcp.cfg01411c.leasefile='/tmp/dhcp.leases'
dhcp.cfg01411c.resolvfile='/tmp/resolv.conf.d/resolv.conf.auto'
dhcp.cfg01411c.localservice='1'
dhcp.cfg01411c.dns_redirect='1'
dhcp.cfg01411c.ednspacket_max='1232'
dhcp.cfg01411c.logqueries='1'

Any help would be appreciated.

I've figured out the issue. I disabled ipv6 on my computer and now it works. How do I disable ipv6 in openwrt so it does not hand out v6 addresses?
