    Hi all,

    it seems that dnsmasq does not exist for AIX.

    Do you know lightweight DNS alternatives for AIX ?

    Thanks

    unbound however there's no package in the toolbox for AIX.

    Good old BIND comes with AIX. Actually, not sure if unbound is considered "lighter" than BIND. unbound/nsd are used together to create a full DNS server where nsd is the authoritative component and unbound is the recursing component. Ran BIND for years on AIX with split zones for enclaved systems. Worked well.

    I guess it depends what you consider "lightweight". dnsmasq does quite a lot, including DHCP. If you're doing a little project, maybe consider spinning up something that runs DNS well, like pfsense/opnsense. unbound is standard there with a nice GUI.

    Very lightweight like a « centralized » /etc/hosts with a few A records.

    I've seen folks copy around hosts files from a central "authorized" copy. It works. It's also how DNS got its start. I wouldn't recommend it.

    We need a service exposing DNS protocol.

    I am trying to understand why AIX shipped bind does not work for your use case?

    What do you mean with "exposing DNS protocol"?

    Then you need to run a centralized DNS server.  It's really easy to produce DNS zones from an /etc/hosts.

    We only need a very very lightweight DNS server in an isolated VLAN that can reply to DNS queries for a few type A records.

    If dnsmasq had been available on AIX it would have been perfect.
