    mcafee firewall record continually attempt connect to my udp ports from dns server



      my Mcafee firewall shows that many continually attempt connection to my udp ports from some dns server as shown in 'mcafee firewall 4.jpg'

      dns.mas.optusnet.com.au is one of the dns servers as shown in 'my dns.jpg'

      sometimes these connections don't appear, only attemp connection to my computer from gateway as shown in 'gateway.jpg'

      it seems my connection speed to internet is slow when these connection appear.

      are these connection from hacker?  why are these attack from dns server? 

      I have to use a dns server to connect to internet.


      I would appreciate your help very much.
