I'm looking for a tool for sketching network diagrams. Ease of use and aesthetic appearance are important. Flats icons or Cisco diagrams icons are would be nice.
My goal is to create networks diagrams with IP subnets, IP address, link connection, different types of machines, and networks symbols. The most important requirement is that the finished diagrams have an aesthetic look in the final output.
It must run on Windows 8/8.1 or/and Mac OSX. The budget is not important.
I know Dia Diagram and Microsoft Visio, but is there a more suitable tool that has specific network element libraries?
