Ah, a free update on the state of the legacy IP address market, from a spammer:
Subject: Spanish IPs ranges available
We currently have a very competitive offer on IP sales, with the following prices:
• €27/IP for ranges from /24 to /22
• €26/IP for ranges of /21 and larger

My wife loves Bookgoblin by Elisabeth Wheatley, and she had an early black friday sale starting today.
But the author has a geoblock on her store which excludes Swiss IPs (and VPNs and Proxies). I couldn't let that stop me. And it didn't.
FOR BOOKHALLA!

Distinct dimensions for attractors of bi-Lipschitz iterated function systems
In this paper, we construct an iterated function system on the line consisting of two bi-Lipschitz contractions whose attractor has distinct lower, Hausdorff, lower box, upper box, and Assouad dimensions, thereby providing negative answers to certain folklore questions. Furthermore, as a by-product of our study of bi-Lipschitz IFSs, we construct IFSs within this family that exhibit interesting fractal behaviour. In particular, we prove the following two statements: (i) There exists a bi-Lipsc…
