The somebug.org Network Test Page

The original version of this page was produced by the operator of the Web site of the Somerville Broadband Users' Group, which operates out of Somerville, Massachusetts (near Boston). It was designed primarily for customers of RCN, a cable TV company that provides cable modem connections to the Internet.

Where am I coming from?

The IP address and hostname shown below are those of the machine originating the request for this page. This machine may be the one sitting in front of you (or maybe under your desk :-), or it may be a proxy cache elsewhere on the network.

Your IP address is: 38.107.191.102 ()

How did I get here?

The following report was produced by running the traceroute command against the IP address shown above. From it, you can determine the path selected at the present moment for traffic between your computer and the site running this utility. You may not get useful results from this report, since traceroute is blocked on some networks.

How fast is my connection?

While we can't measure the raw speed -- or bandwidth -- of your connection, we can measure the latency, or delay, of the connection. Latency can impact the speed of Web browsing, voice conferencing, and other activities. We will send 40 pings to 38.107.191.102, which will take at least 40 seconds to complete.

How can I make this page available at another Web site?

If you run a Web site and would like to make the netdiag page available there, you can download the Perl source of this version from ftp://bioc09.uthscsa.edu/pub/gst/netdiag.tgz, and the original from ftp://ftp.somebug.org/pub/netdiag/netdiag.tar.gz.

If you do make netdiag available elsewhere, send email to lars@larsshack.org to let Lars know. He'll list your page on the "somebug" site for those who want a second opinion.

Are there other sites like this one?

traceroute.org maintains a list of sites that will provide traceroutes back to your host (or, in some cases, to any arbitrary IP address).
