The randomly changing prefix is really annoying. There's no reason for your ISP to do this other than to try and upsell you on expensive commercial services.
- convolvatron 2y agoThis was done so that networks could actually be renumbered to increase aggregation and routing efficacy. In todays work once you give out a number you cant take it back, and that leads to fragmentation (i.e. the swamp)
- simoncion 2y ago> In todays work once you give out a number you cant take it back This isn't true. If it were, then home ISPs would never renumber client networks. You're probably thinking about the larger allocations handed to folks who have ASNs, rather than the small allocations handed small ISP customer sites... and even then, those can totally be reclaimed.
