Welcome to DIMES!

What does the Internet look like? How does it evolve?

DIMES is a distributed scientific research project, aimed to study the structure and topology of the Internet, with the help of a volunteer community (similar in spirit to projects such as SETI@Home).

We are welcoming DIMES pioneers who want to participate in our initial measurement effort and help us discover the Internet. If you want to suggest ideas or comment on DIMES you are welcome to visit our forums
