I have campus network with 9300 and 9500 series switches. one 9500 switch sits as DNS Proxy and all users` DNS addresses are pointed to it and everything works fine. But, if I point it in my other switches it is not working. Even I try to address manual IP host command it does not work.
ip host tools.cisco.com 18.104.22.168 ip name-server 22.214.171.124 ip domain name orkhan.local
Yes, I have connectivity to both my internal DNS Proxy and 126.96.36.199.

% No valid route for destination Success rate is 0 percent (0/1)
