  • Invalid class in dns query

    From Trevor Woolley@21:1/5 to All on Wed Aug 5 10:46:59 2020
    Hi all,

    Looking for a temporary work around, while an issue gets resolved. I have a
    DNS query coming in with an invalid class requested (65 or 0x41).

    The workaround I’m looking for is one that just uses the IN class (1 or 0x01), if I have to duplicate all records required into “CLASS65” it could be a lengthy process.

    Currently running BIND 9.14.5 on a Centos7 OS.

    Rgds

    The only classes ever assigned were 1, 2, 3, 4, and pseudo-classes 254 and 255.

    What is class 65 supposed to be? Why would anything that wasn't totally broken query for it?

    R's,

    It was coming from a broken device in pre-deployment testing.

    My advice to Trevor, when I rang him, was send it back to the manufacture to be fixed and there is no workaround for this fault in named.
