If I understand your question properly, you do not want DNS resolution.  If that is the request, simply add a "-n" to your traceroute command and that will turn off DNS lookup.

Thanks Craig,

How can i resolve it without using -n ? the client says for other public ip's while he traceroute , he doesnt see the hostnames ?

Is it something, that i should filter in the firewall, as the policies are filtered through SRX in DC ?

If you were to filter the DNS resolution at the firewall, you would likely filter all DNS for the host that is doing the traceroute.  Traceroute's default is to do the resolution for all possible addresses.  Is your client performing the traceroute from a different OS?
