I was just wondering because I had the same IP address for at least the past 4 years, it was 69.207.72.172. Then, I used my router to change it to .172.72 just for fun and it worked . . For like 3 days. Then it just wouldn't connect. I set it back to dynamic and it went back to the same old IP. Now, I've been switched to 24.x.x.x and it's been like that for a while and even when setting it to statically use that IP, it will soon after lose connection, then go right back to the same one using the dynamic setting! Why does that happen, and if they use dynamic IPs, then why did I have the same one for so long? I have Roadrunner from Time Warner with 10 Mbit/s Download and 1 Mbit/s upload,
