I have a Raspberry Pi 4 connected to my Bipac router via Ethernet. I am using this Pi as an external Web server so I have set a static IP address on the Bipac for it. However, I now find that on machines attached to my local WAN and LAN that they can't access the Pi by hostname. They can only access it by IP address. I have configured all devices on my local network to use the Bipac as their DNS server.
I have set the IP address of my Pi 4 to 192.168.1.11 and I get the following on a typical machine on my local network:
$ dig raspberrypi

Because I've put the IP address of the Pi 4 in some machines' /etc/hosts files I do get the following:
$ ping -c 3 raspberrypi

But, not all machines support a hosts file. Also, why do I have to manually add this in the first place?
Here are 2 example hosts on the same home network, one on the WAN and one on the Ethernet LAN -

Any idea why the Bipac isn't resolving the static IP address of an attached device to its hostname?
Bipac 8800AXL R2 does not return hostname for static IP address on Ethernet port

Bingo! That did the trick. Thanks.
