[address-policy-wg] Getting LIR

Hello, sorry for the inconvenience if this is the wrong place for this kind of question. In this case please be so kind and point me to the right place. We are thinking about getting a LIR and I need some informations about the requirements we need to fulfil. I know documents about requirements of getting PI and ASN but for getting LIR and tho PA i feel a bit clumsy.. :-) Thank you! best wishes, Danica
