"Retro" Puppy. Puppy 2.16 (and earlier) uses the 188.8.131.52 kernel. Puppy 2.17 uses the 184.108.40.206 kernel, whereas Puppy 3.00 and 3.01 use the 220.127.116.11 kernel. The problem is that the kernel underwent major structural changes between the 2.6.18.x and 2.6.21.x series and some people find that Puppy will not boot (or had other hardware-related issues) with the later series. Well, a couple of people anyway. Although this is a small group, I decided to support them by offering the latest Puppy but with the older kernel.
