Just asking for another help, if you can. I was analysing my DNS traffic using tcpdump (not verbose mode) in a AIX client. I found that a lot of repeat of transaction IDs over matter of hours. Is it expected?

Code:
22:39:52.301965 IP 192.168.1.119.56880 > 192.168.1.126.53: 49968+ A? shavar.services.mozilla.com. (45)

Net::DNS::RR::APL(3)					User Contributed Perl Documentation				      Net::DNS::RR::APL(3)

NAME
Net::DNS::RR::APL - DNS APL resource record SYNOPSIS
use Net::DNS; $rr = new Net::DNS::RR('name IN APL aplist'); DESCRIPTION
DNS Address Prefix List (APL) record METHODS
The available methods are those inherited from the base class augmented by the type-specific methods defined in this package. Use of undocumented package features or direct access to internal data structures is discouraged and could result in program termination or other unpredictable behaviour. aplist @aplist = $rr->aplist; @aplist = $rr->aplist( '1:192.168.32.0/21', '!1:192.168.38.0/28' ); @aplist = $rr->aplist( '1:224.0.0.0/4', '2:FF00:0:0:0:0:0:0:0/8' ); @aplist = $rr->aplist( negate => 1, family => 1, address => '192.168.38.0', prefix => 28, ); Ordered, possibly empty, list of address prefix items. Additional items, if present, are appended to the existing list with neither prefix aggregation nor reordering. Net::DNS::RR::APL::Item Each element of the prefix list is a Net::DNS::RR::APL::Item object which is inextricably bound to the APL record which created it. negate $rr->negate(0); $rr->negate(1); if ( $rr->negate ) { ... } Boolean attribute indicating the prefix to be an address range exclusion. family $family = $rr->family; Address family discriminant. prefix $prefix = $rr->prefix; Number of bits comprising the address prefix. address $address = $object->address; Address portion of the prefix list item. string $string = $object->string; Returns the prefix list item in the form required in zone files.
