How to Disable DNS Lookup in Cisco

When a Cisco router is initially configured, the router’s DNS lookup function is enabled by default. This function is only useful if the router utilizes a DNS server on the network; otherwise, it will cause delays to users. When an erroneous URL is typed, the DNS lookup function will attempt to find the URL on the DNS server. If no DNS server is available, the user’s computer will hang while the lookup is performed. To decrease user delays if no DNS server is configured, disable the DNS lookup function on the Cisco router.
