When Hurricane Ike caused massive wind speeds and damage to the midwest, we were without power from Sunday to Thursday due to all the downed power lines all over the state. I ran a laptop, wireless router, and cable modem off of a 300watt inverter plugged into my car the entire time. I had to go outside and run the car for 30 minutes every 12 hours to keep the battery charged but I never once lost internet access. The neighbors couldn't believe I still had working high-speed internet access in that kinda situation.
No. Dotted-decimal notation is the only acceptable way to represent an IPv4 address in a URI according to RFC 3986. That RFC even specifically mentions that many implementations that process URIs make use of platform-dependent system routines, such as gethostbyname() and inet_aton(), to translate the string literal to an actual IP address and that may allow ways around filtering software.
If it is explicitly against the RFC then browsers shouldn't allow it.
