regarding dnsmasq

    I would like to setup custom entries to the DNS cache on the router.
    for instance, I have a pap2 device that uses the IP. I would like to address this device as http://pap2 in my web browser instead of or ping it as pap2 and not its IP address.
    I understand I can do this with dnsmasq but I am not sure how...
    Can someone point me in the right direction?
    Thanks a lot!

    This works for me:- (and has done since HyperWRT Thibor days)

    Give your router a local domain name - call it router.lan for example. Then give your device a static dhcp assignment with name pap2.lan.

    Then with default settings dnsmasq will add the ".lan" when you ask for "pap2" and give you the correct IP address.

    dnsmasq has so many options, I'm sure there are other ways too!

    Basic > Router Identification
    Domain Name: foo

    Basic > Static DHCP
    00:90:D0:AA:AA:AA MODEM

    ( easiest to click on [static] in Device List )

    then ...

    # arp
    MODEM.foo ( at 00:90:D0:AA:AA:AA [ether] on vlan1

    # arping -I vlan1 -c5 modem
    ARPING to from via vlan1

    setting the domain name to lan and adding devices to the static list was enough actually. Thanks!
