NSLookup flags an invalid domain, yet Ping functions correctly (found during Wireguard configuration).
I was configuring a WireGuard server for remote access and began troubleshooting local hostname resolution. Only certain devices I had set up were working. I redirected the WireGuard DNS to my home router to streamline things, thinking the issue was resolved. However, testing without the VPN still caused problems, leading me to suspect another network-related problem rather than the VPN itself. I removed the VPN and used NSLOOKUP on my router’s devices page, finding that only about half were recognized, with the other half returning an error about a non-existent domain. Despite this, pings to all devices worked fine. I initially considered a DHCP conflict, but discovered some hostnames resolved outside DHCP ranges while others were inside. I verified there were two DHCP servers, but only my home router appeared in the IP lookup commands. This was confusing since I could still reach other machines on Linux, Mac, and Windows. As a beginner, I’m unsure what to do next—any guidance would be invaluable! [EDIT]: After some adjustments and DNS mapping in my router, all servers show up, but connecting via WireGuard still blocks internet access. It feels like progress, yet the final step is frustrating.]
It looks like your home router might have a significant problem. The term "router" can refer to many different devices, so being specific is important.
