    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=E2=80=99m looking for is one that just uses the IN class (=
    1 or
    0x01), if I have to duplicate all records required into =E2=80=9CCLASS65=E2= =80=9D it could
    be a lengthy process.

    Currently running BIND 9.14.5 on a Centos7 OS.

    Rgds
    Trevor

    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,
    John

    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.
