Last time I checked, APNIC don't issue anything smaller than about a /22, and they demand very, good justification for why you need so many IPs and can't use NAT, name-based vhosting, etc. You're not going to get this for anything less than a medium--size ISP or hosting business - certainly not for a SOHO connection > 2. Apply for AS Number from APNIC. Last time I went through this process, it took several months for approval, and required joining APNIC first. IIRC, that was in the vicinity of US$1000 - again, not exactly suitable for a SOHO Again, you need to show good cause why you need your own AS - having your own portable /24 or bigger, and having that netblock multihomed, will be sufficient reason though. > > 3. Talk to your ISPs for set up. (Your ISP must also be AS). Also, you'll have to get a router with enough RAM to hold the global BGP table, or have an arrangment with both your ISPs to have them only forward you a section of the table. Oh yes, you'll need to discuss this with both your ISPs in advance as well - again, they will probably only even think about doing this kind of setup for you if you're a large customer - it's annoyingly complex to set up, and very non-standard, so a high maintenance cost as well. Lets not talk about the overhead of keeping the tables in sync on a small connection either... Lastly - the global BGP table is already polluted enough because Telstra don't know how to aggregate their blocks. If every man and his dog started getting their own AS just to try to have a few less outages on their ADSL connections... dammit, it's 8:34 already and my lift is here, have to run :( -- There is nothing more worthy of contempt than a man who quotes himself - Zhasper, 2005 -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
