There is a squid process listening on a random port with protocol udp each time I start squid and I'm not sure what it does.

I do a "ps -ef | grep squid" and get
root     22110     1  0 18:24 ?        00:00:00 /usr/sbin/squid3 -D -sYC
proxy    22113 22110  0 18:24 ?        00:00:00 (squid) -D -sYC
I do a "sudo netstat -tlnup | grep squid" and get
tcp        0      0 *               LISTEN      22113/(squid)
udp        0      0 *                           22113/(squid)
I'm ok with the one listening on, but what does the process do that's listening on

I checked syslog and found, "DNS Socket created at, port 36947, FD 8". Is this a DNS process of some sort? Can I disable it? If not, is there a way for me to make it listen on a specific ip or interface instead of

I already disabled the icp process so it doesn't show up.
