This range-based approach makes troubleshooting easier: pinging an IP rules out DNS/mDNS resolution issues, router and firewall logs become readable since addresses stop moving, bandwidth graphs can be mapped to specific devices even after lease renewals, and any device with an address outside the defined ranges immediately stands out as suspicious. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why does pinging a device by IP address help troubleshoot network issues instead of using its hostname? Pinging the IP address rules out DNS or mDNS resolution problems as the cause. A device can be online and fully reachable, but if its hostname fails to resolve over mDNS or local DNS, it looks identical to a device that is actually down. If the IP responds, the issue is name resolution, not the device itself, saving time otherwise wasted troubleshooting the wrong thing. _daily.dev surfaces networking troubleshooting techniques like this for people managing home labs._ ### Why do router and firewall logs become more useful after switching from DHCP to fixed IP addresses? Router and firewall logs record activity by IP address rather than hostname, so once addresses stop changing, log entries can be reliably traced back to specific devices without cross-referencing. This made it possible to identify a Home Assistant integration repeatedly hammering a device and to diagnose a port-forwarding rule that had silently stopped matching traffic to a media server. _Developers debugging network logs can find similar real-world fixes on daily.dev._ ### Why does a DHCP-only network make bandwidth monitoring unreliable on a router's traffic graph? On a DHCP-only network, a bandwidth spike traced to an IP address becomes meaningless once that device's lease is renewed and the address gets reassigned, since the graph shows an address that may no longer belong to the offending device. Assigning fixed addresses keeps spikes mapped permanently to the correct device, making bandwidth hogs easy to identify. _For readers tuning home network performance, daily.dev tracks practical fixes like this one._ ## Similar posts on daily.dev -
