If there is only ever one "___" in a value you could generate all 6
possibilities from hash1 and look them up directly in hash2.

if ($hash2{'___.666.fff.jjj.ccc.222'} or
    $hash2{'111.___.fff.jjj.ccc.222'} or
    $hash2{'111.666.___.jjj.ccc.222'} or
    $hash2{'111.666.fff.___.ccc.222'} or
    $hash2{'111.666.fff.jjj.___.222'} or
    $hash2{'111.666.fff.jjj.ccc.___'}
    ){ warn "found it!" }
