My router runs OPNSense Business. I like having an open-source router, but I have a few gripes with it. My biggest issue is that, by default, OPNsense can’t resolve hostnames on my local network. Why can’t OPNsense resolve local hostnames? For every other router I’ve owned in my life, if there’s a computer on my network named foo123 and I run ping foo123 from my main desktop, then everything just works. My desktop successfully pings foo123.| mtlynch.io
This document specifies the behavior that is expected from the Domain Name System with regard to DNS queries for names ending with '.home.arpa.' and designates this domain as a special-use domain name. 'home.arpa.' is designated for non-unique use in residential home networks. The Home Networking Control Protocol (HNCP) is updated to use the 'home.arpa.' domain instead of '.home'.| IETF Datatracker
