I'm currently in the process of working on a "rough draft" of a policy on IP number usage. I'd like to solicit a few comments from those of you who seem to be making the majority of the routing decisions. Here's a copy of what I'm presently working on. Please feel free to rip it to shreds if necessary.... THE MONTANA INTERNET COOPERATIVE INTERNET ADDRESS ASSIGNMENT AND ROUTING POLICY September 29, 1995 Standard Dialup SLIP, CSLIP and PPP customers will be allocated a Single Static IP Address to be used to configure their software. There are many advantages to be gained by Statically allocating the numbers, including the ability to have multiple mailboxes by using SMTP, etc. Dedicated and Routed-Dialup customers will be allocated a block of numbers from MIC's CIDR block. The size and quantity of blocks will depend on the number of machines to be connected to the network at the customer's premises and the customer's network architecture. MIC currently allocates blocks containing 8, 16, 32, 64 or 256 "individual" addresses. Multiple consecutive blocks will be allocated depending on need of the customer. Dedicated and Routed-Dialup customers who already have a set of Internic allocated addresses may continue to use those numbers as long as the following conditions are met: 1) The numbers MUST be listed and registered in the internic database. 2) Only blocks addressable with a prefix of /21 or smaller for addresses with an initial octet less than 205, and blocks addressable with a prefix of /19 or smaller for addresses with an initial octet of 205 or higher will be permitted. If you are uncertain whether certain addresses meet these criteria, contact MIC support for details. 3) The customer is aware that MIC will not guarantee the routablity of any customer provided numbers. The customer should also be aware that routing policies can and will change, and as a result, the customer's numbers may not be routed by various Service Providers at any point in the future. forrestc@imach.com
