DNS traffic is name resolution queries.. it happens every time you are querying a domain.  I do not see a way to avoid it nor an easy way to reduce it.

DNS = Domain Name Service

thanks for you replay

but read it may slow down internet
DNS is needed for the internet to work.

Lets say you wont to go to www.yahoo.com.  How does your computer connect to that site.
Since we are running IP we will need an IP Address.  To get the IP Address your computer/proxy will do a dns lookup for the A Record for www.yahoo.com, the reply will be one or more IP Address for the site.  Your computer know knows the address of the server and can now send a packet to it.

Its like a phone call.  You want to make a phone call to your friend Bob.  In order for you to call him you need his phone number, so you look up the phone book and get his number then dial his number, not his name.

So save you time, you write down bobs phone number for next time, thus saving a look in the phone book.  This can be done with a local DNS Server (your personal phone book).
DNS traffic is name resolution queries.. it happens every time you are querying a domain and also if you have multiple DNS server, there will be replication of zones between the DNS servers which will cause the DNS traffic too.

To reduce DNS traffic, you will need to properly plan your DNS server, interm of how the replication between DNS server, how DNS queries are being routed from client to DNS server and any DNS queries to be forward to any DNS servers.
