IPv4 smaller than /24 leasing?
And this is exactly what other companies are doing. The traditional way of doing a startup ISP is:
1.You get provider assigned IP space
2.You grow big enough to get your own IP space, historically from ARIN. Nowadays you have to buy it on the open market.
3.You re-adddress your network for the IP space you have.
4.Chewing up the /24 when you may not too in order to meet justification.
So now, we have a startups and growing ISPs. I have multiple clients who are in the exact same scenario I am going to describe.
They are a startup and canâ??t justify a /24 so they hope to find two backbone providers to play ball. They hope one will assign them a full /24 so they can participate in BGP. That provider is probably charging them $1 per IP per month. Okay fine, pay it. As said in a previous e-mail, if they canâ??t afford it they shouldnâ??t be in business right? They go through the ARIN process to get an ASN and can now participate in BGP. Great, they bring up BGP and work towards having the cash flow to buy a /24 on the open market. Again, if they canâ??t afford to play they shouldnâ??t be in business right? Cash flow pays for the ability to buy a /24 in 8-14 months. $4,000 plus the $2500 they spent on leasing fees. Again, if they canâ??t afford it donâ??t play huh?
So now, they have a /24 they really donâ??t need. In order to meet ARIN justification they hand out IPs to people who really arenâ??t in their business model just to meet justification. Before you know it they are using 80% of a /24 when they really only need half or less of it. The /24 is too small to scale of giving everyone publics, so their network design is centered around 1: many NAT, CGN, and other such things.
How is this a good use of resources when they have to justify 80% of a /24 in which they only need half of? I have 5 ISPs I work with that have 300-500 customer and are using a /26 or smaller of IP space. They canâ??t have true redundancy they are able to manage because they canâ??t do BGP themselves. So they are tied to one ISP because thats where they get their space from. Or, going back to the original part of this thread, they lease from someone across a tunnel. Even then, they are still tied to someone.
