7. Your Public IP Address


8. Online Diagram Drawing Sites

  • https://www.draw.io/ : it supports to save diagram to all kinds of Internet online drivers. So far, I found it is best to make network diagram. It is completely free to use for any purpose, there is no premium pay-for functionality, watermarking, or other limitations. You own the content you produce with draw.io and may use it for any purpose, including commercially.
  • Gliffy :After trial, it is still free to use, but not able to create a new diagram. Existing diagrams will still be kept for editing. Gliffy marks all diagrams as public when a trial expires. Any diagrams created would remain in the account. Diagrams always remain in the account regardless of the status. Gliffy never moves or deletes diagrams. Free account have a limit of 2MB or 5 diagrams, but usually it is enough since you export to gliffy format to import it later. 
  • Lucid Chart. It can import /export visio format file. Free account will limit complexity to only 60 objects, three active documents, 25mb of Storage, not able to edit imported visio files, etc. 
  • http://asciiflow.com/
  • SmartDraw :  provides desktop version, not free. For Cloud , trial for only 7 days, no free usage. 
  • https://cloudcraft.co/ : Best for AWS diagrams. It also gives you a budget number for your AWS infrastructure. Please check this post.
