IPIP.NET (https://www.ipip.net/) focuses on IP geographic location and research, sorting and distribution of IP portrait data. Our main product IP geographic location database is based on BGP/ASN data and network monitoring points all over the world for city-level IP geographic data annotation. There is a list of useful tools for exploring today's IP-based Internet. For example, you can experience with online Ping, WebPing, ASN lookup, DNS resolution, IPv6 test, etc. Referring to our lectures about today's Internet, with the helpful tools from ipip.net website, please try to explore and investigate deeper into how current Internet is organized in a local area or under some specific ISP. Please write a report presenting your experiments and results, with any meaningful discovery highlighted. Please list the network objects (ip, domain name, subnet, server, etc.) that you have investigated. Your results should be well annotated and discussed, other than just the screenshots.
