I'm running an openwrt like firmware on my Access Points but i cant figure out how to ping hostnames rather than ip adresses. (locally)
If at all possible i'd prefer not to install anything. (definitely not something that could impact the functioning of the Access Points.
Creating something like a dns server is not feasible for me.
is there any way as to ping hostnames rather than ip addresses?
then it's not openwrt , and the version doesn't seem to match any LEDE releases.
LEDE is EOL since 3 years or so, when it merged back to/with openwrt.
if you don't have a local DNS, for the DHCP could update, you'll need to put entries in the hosts file(s).
That won't work until you set static IPs to all the devices, either by reconfiguring them to use fixed IPs, or static leases from the DHCP.
I haven't worked with mDNS, but it seems the clients have to support it, to be able to utilize it.
if your clients do, then go for it.
Most people/setups rely on DNSes on internet (google, opendns, cloudflare, etc) or provided by ISP.
Those DNSes have no clue about what's going on in your network, so you need an internal DNS, covering your own LAN.
