The iThena distributed project concerns experimental mapping of network structures included in the Internet. The project is in closed beta phase. Currently, the only application available in the project (iThena CNode) performs a sequence of traceroute procedures from client computers. The resulting data is sent back to the server and submitted to the main database, where it can be further analyzed.

Currently the main supported and recommended platform is x86_64-pc-linux-gnu, windows_intelx86 and windows_x86_64. After joining the project, accept the download of test/beta applications in the settings (all currently applications is in a Beta stage). This can be changed by checking the appropriate box 'Run test applications?' in 'iThena preferences' in your profile after logging in.

Network structure mapping summaries will be available online.

Two applications are currently active: iThena CNode and iThena PERF.
The iThena CNode application tests delays, possible losses and routing of network packets.
The iThena PERF application mainly tests bandwidth to defined endpoints.

Dedicated DNS servers available (as part of optimization)
Applications (especially CNode) can now make significant use of DNS servers.

To avoid overloading other servers (not necessarily your ISP) you can use our DNS servers:

Location: Germany/Frankfurt
IPv6: 2001:41d0:701:1100::452

Location: Canada/Beauharnois
IPv6: 2607:5300:101:0:0:0:0:75d

Location: Poland/Warsaw
IPv6: fe80::250:56ff:fea9:8da0

Location: Australia/Sydney
IPv6: 2402:1f00:8100:400::125a

You can also set up your own DNS server (or just DNS cache) on your LAN.
This is especially important if you have several/many BOINC clients and CNode app.
You can check which of the above DNS will be the best (geolocation).
