Dear Anela, If the 2nd AS will have a different routing policy from the first one then you can go ahead and request it from us. As for what block of IP addresses to use- you can either use your existing address space, or if this AS will really grow and you expect to use a lot of IP addresses for it in the future, you might want to set up a separate registry for it. By the way, there was a request about returning of AS numbers. If you received an AS number and the plans changed so that it is no longer needed, please contact hostmaster@ripe.net to return it. If however, you do have plans to re-establish a multihomed connection in the near future, you can hold on to the number until then. I'd recommend contacting hostmaster anyway to explain the situation.
