Intermittent DNS

I'm having issues with intermittent DNS in my Amahi (my router DHCP server is off). When I type the IP address, for instance:
http://192.168.1.1
I get to the Amahi dashboard nearly instantly
When I type:
http://hda
It often times out or requires multiple refreshes.
I'm not sure where to start trouble shooting: router or Amahi?

Thanks, that was a helpful guide, though it did not help me solve the problem. Here's the log from the troubleshooting guide:

You are not using IPV6 are you in your network? Amahi does not work with it.

I have a feeling I am... When I run a WHOIS I get an IPv6... How can I check and what causes this: router or something I messed up in Amahi?
Thanks for your help.

I think I fixed it!

I would imagine it's your router.
You said you think you fixed it, so can we close this thread now?
