The year 2003 was also the year in which unsolicited e-mail, or "spam," became a major problem for all Internet users. Various filtering systems have thankfully been devised and deployed, but this problem has no easy solution. It will be interesting to see what impact new antispam legislation will have over the coming months and years.
The first article presents an in-depth look at the IP Version 4 address space and its measured and projected consumption rate.

Which brings us to the IPJ publication schedule. If you are a regular subscriber to the IPJ, you probably have noticed a somewhat irregular publishing schedule in 2003. This December 2003 issue is indeed being published in January 2004. This results from our effort to produce timely quality articles in a world where the experts are not staff writers. Of course, you should still expect to receive four issues per year, and your feedback to firstname.lastname@example.org will help make IPJ even better.
