I read somewhere that the IOS I'm using recognises domain names, so I was wondering if it is possible to create a master blacklist of domains and store the list in a text file on the flash, and then create a rule that will deny/block access to any domain in the list. Can this be done?
If not, is there any other (easy) way to block a large number of domains? - preferably something that can be easily updated and added to.
