As a networking guy ( I make the IQrouter that fixes Bufferbloat
), there are actually several ways to do this.
But to your point, that is because most routers use the MAC address of the client to calculate an IP selection from the DHCP pool, so the device is likely to get the same IP from that router, even if it's been disconnected for a few days. But it is not a reliable thing, as any other device, whose MAC would result in a similar hash, might now get that IP. So when the original device is reconnected, the router has to give it a different IP. Therefore, the unreliability of DHCP assigned IPs.
Another way of doing this is (if your router supports it), is to make the currently assigned IP into a Static Lease, basically locking that IP to that MAC. So even though it's all still DHCP, the router has 'reserved' that IP for that device, and it's guaranteed to stay fixed.
But all of the above breaks when you replace the router, or make significant network changes.
Depending on Bonjour/mDNS is much cleaner as it will always work based on the name. Kind of like why we don't ever need to type the IP for AVSforum.com
I thought it would also make helping others much easier, just give Marantz-AV8802.local.
as the URL to the UI without the need to caveat and explain how to find the IP or suggest the use of static IPs.
