ip dns server ... I have the DNS server configured as follows:
ip dns server view-group dnsVLcustom
ip dns view-list dnsVLcustom
view dnsVcustom 1
ip dns view dnsVcustom
no domain lookup
dns forwarder 18.104.22.168
dns forwarder 22.214.171.124
... is there a way to set something like this ?
rad.msn.com ---> n.n.n.n
spam.whatever.com ---> n.n.n.n
ads.whatever.com ---> n.n.n.n
... ie: don't forward for these domains, just return n.n.n.n
My current config has all those unwanted sites filtered by the incoming ACL but they are hard-coded by their IP addresses.
Problem is I am adding more unwanted domains and the ACL is getting bigger and (I presume) this will slow down everything -not to mention I can't be aware of IP changes.
It would be really good to have just one IP on this ACL for unwanted traffic stopping it right after entering the routers instead of a cumbersome hard-coded ACL.
Any suggestion ?
