Cisco 1700

[crmayer]

Can somebody tell me how to change the DNS Server on a Cisco 1700?

 

[mjmartino]

in privilege mode type
"no ip name-server xxx.xxx.xxx.xxx"
to remove the old name server then
"ip name-server xxx.xxx.xxx.xxx"
to list the new

unless you are talking about a DNS server for dhcp or VPN

I am talking about DNS Server for Dhcp.

 

[mjmartino]

I am assuming you mean that the cisco is the dhcp server and in that case you would change it the way I showed you. dhcp will then hand those dns servers to the clients.

I need to change the 64.233... since we changed ISP's. But when I do a show name-server is lists 255.255.255.255...

The dns-server above is the one that i need to change.

router(config)#ip dhcp pool exec
router(dhcp-config)#no dns-server 64.233.72.10
router(dhcp-config)#dns-server (new DNS server IP Address)
router(dhcp-config)#exit
router(config)#exit
