2.       ip.addr==10.0.0.1  && ip.addr==10.0.0.2 [sets a conversation filter between the two defined IP addresses]

3.       http or dns [sets a filter to display all http and dns]

4.       tcp.port==4000 [sets a filter for any TCP packet with 4000 as a source or dest port]

5.       tcp.flags.reset==1 [displays all TCP resets]

6.       http.request [displays all HTTP GET requests]
