All, I have a customer that would like to setup two different sites...one in the US and one in the UK. These sites will be mutually exclusive so that they won't be load balancing between the two, the custom app that they will be running on the web servers will direct UK customers to the UK and US customers to the US. However they would like the US site to be a backup site for the UK. So that if there are any problems, the UK traffic will be routed to the US via bgp. My question is this. Can a company use the same AS globally and announce the same addresses out both Europe and the US if the ASN and NetBlocks were allocated from ARIN? They want to be able to take the addresses that they are announcing in their UK location, and announce them out of the US(in case of a disaster, for example), so that their UK customers can still get to a limited version of their site. Are there any problems with using ARIN allocated IP addresses anywhere in the world? I know this works technically, I'm just curious if any of the ISPs out there are filtering to keep European traffic limited to RIPE allocated IP addresses. And are there any problems of doing the same thing in Asia? Mike Smith __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!
