@Robie Basak (racb):
Thanks for your response and sorry I responded late.
I didn't know it wasn't a problem.
All I knew is that DNS port is 53.. so naturally I thought that something weird
happens..

Title:
dnsmasq uses many ports
Status in dnsmasq package in Ubuntu:
New
Bug description:
The steps required to see that dnsmasq uses many ports are as follows:
1. Open the browser (e.g. Firefox)
2. Quickly open many websites on different tabs (3 websites are enough in
my case)
3. The connection is slow, so it takes some time until it connects to the
websites.
4. Before any connection to the website is made, execute:
sudo netstat -veepa -n -W
and the following ports will appear (some output was omitted for
clarity):
