I think the NCC should do the following: 1-inform anyone who asks for a block of networks that if different guarded fields are needed in the future then splitted blocks have to be registered. 2-only the same people who has registered the block can request the splitting. 3-inforce the above rules in database registration software. ---------- ---------- Antonio_Blasco Bonito E-Mail: bonito at nis.garr.it GARR - Network Information Service c=it;a=garr;p=garr;o=nis;s=bonito c/o CNUCE - Istituto del CNR Tel: +39 (50) 593246 Via S.
