Re: Hitron Router CODA-4582U how to use local hostname?
When you set up the modem, you may have come across a data entry for the local host: hitronhub.home That suffix is appended to the nslookup query, causing it to fail on the first query. Nslookup appears to run a secondary query without the appended suffix, and that is what you see for the nslookup results.
So, just to see if this works, instead of using "mydevice.local", try "mydevice.home".
Fwiw, your the first person who've ever asked about using the "mydevice.local" address. Have you been using this with another modem and just switched over to the 4582, where it doesn't appear to work? Was the previous modem a Hitron modem or another modem altogether? In either case, do you happen to know the model of the previous modem?
In theory the 4582 is a new modem, but, I wonder about the amount of code reuse from previous Hitron modems. Maybe this is a specific case where the previous code wasn't reused.
