--=====================_53511942==_.ALT Content-Type: text/plain; charset="us-ascii"; format=flowed Okay, everyone. I will explain. Some ISP's don't run their own network. That's what I meant by the previous message that seemed to get me into a whirlwind of who is on first, or third for that matter. They are using other services that charge them to use it and in turn they must charge their customers. Each ISP that starts out may host "virtually" with a trunk line that has a Class C of numbers. There are 255 numbers in each but several sections of these numbers are specified as system, server or co-located equipment, hardware and such. On the other hand, an ISP can decide to do it themselves which allows for better control and cost. Since with my trunk provider I can add Class C's at any time, my limit for each Class C is 255 numbers but can grow. Most customers don't even know why they would want the same IP address each time they dial in. VPN's use them exclusively because of the nature of their business. ISP's use several ways to get an IP address. Since most of my dial in IP addresses are assigned by my POP provider, it allows me to do as I need for those dialing in with one of my static IP's. Having a random dynamic IP address allows for certain scripts to be run to drop users or free up IP addresses for the services being run at any given time on a server. Because POP providers use a variety of sources for IP addresses, each one may have 100 Class C's running through their modem bank and only charge for those that specify a static from the radius server being called upon. Most POP or trunk providers charge a sizable fee for static IP's but I am not charged that much. Just a note, a static IP can be given to a connected computer (at the hub) or at time of dial in. If I assign you a static IP for an ftp server, it's always that IP address until you change it or I cancel it on my side. No one else is able to use it for any reason. I believe that this may limit me to 200 users with static IP's, but think of it this way, I can always get more and the percentage of people who want these things are about 5% of any customer base. I have only assigned six static IP's in any given year. Someone would have to know how and what to use it for. My neighbor or sister hasn't a clue what this even means. For those of you who want a static IP address it's normally given out with services rendered. Some companies choose to nickle and dime customers for extra features that cost me little to provide. I would rather have lot's of dial in accounts with a few static IP's, lot's of co-locations, lot's of websites and such, rather than charging for each email, each dial in, each service needed. So, there you have it.

Well, see, thereby hangs a tail....providers *should* squash the non
routeable addresses before sending them on. If you get this traffic
on your inbound ethX card, you know someone is up to no good and your
ISP is likely to suffer evil RSN. It's been a bit since I've seen a
report of this, but they are there.
