Download Portolan Client from the Google Play Store at https://play.google.com/store/apps/details?id=it.unipi.iet.portolan.traceroute
Please note that the Portolan app has only been tested on standard Android versions. Installing the app on modified Android versions could lead to unexpected behaviour.
First, a pop-up window is displayed, containing information about the application. Press the “I Agree” to start Portolan or “Discard” if you don’t wish to take part in the Portolan project.
The home screen is a simple menu where you can select several measurements that you can perform from your network: diagnostic tools, speedtests and RSSI.
Once started, Portolan automatically performs measurements for the Portolan project. It periodically connects to our servers to retrieve any measurement tasks it needs to perform. If a task is received, the application carries out measurements and sends the results back to the server. Data stored on the servers is completely anonymous. No personal data is collected.

2.1. Network diagnostic
The measurements that you can perform are:
Performs a traceroute compliant with the Paris traceroute algorithm, which is able to detect the presence of load balancers in the traversed path. Optionally one can use the Multipath Detection Algorithm, which is able to discover all the available paths between the source and the destination.
- AS Traceroute
Performs an AS Path traceroute that lists the traversed Autonomous Systems (ASes) instead of the IP interfaces.
Sends UDP/ICMP probes to check the reachability of the given target IP address or domain name.
- Connection details
Tests the received signal strength and returns information about your cellular and WiFi connection.
- Subnet calculator
This tool is an easy-to-use IP subnet calculator that allows you to calculate every aspect of your subnet configuration.
- DNS lookup
This tool finds information about a domain name or IP address. The IP-to-AS mapping is performed using BGP datasets provided by the Isolario Project. The geolocation of IP addresses and of ASes is performed using MaxMind’s GeoIP Lite database.
- Subnet scan
This tool scans IP addresses belonging to your WiFi network, for finding which are allocated and their open ports.
Scans a domain name or an IP address discover active services and open ports.
- For Traceroute, AS Traceroute and Ping you can set several parameters via the settings screen.
This tool provides a report on DNS records for a specified domain or hostname.
Two speed tests are available in Portolan:
- Max Throughput Estimation
Estimates the Maximum Throughput that can be achieved along an Internet path whose end points are your smartphone and the Portolan server located in Pisa, Italy.
- BitTorrent test
With this tool you can test if your ISP is shaping your BitTorrent traffic.
With RSSI Tracker you can start/stop a signal coverage tracing along your path.
