This read-write INTEGER selects the organizational scope, localNetwork(1) or global(15), that limits how far a registered address's reachability information is distributed, defaulting to localNetwork(1) for ATM group addresses and global(15) for individual addresses. An administrator sets this to control leakage of routing information beyond an intended boundary, since the description states the address information must not be distributed outside the indicated scope. For example, a carrier restricts an internal group address to localNetwork(1) so it is never advertised to other networks, while leaving a public individual address at global(15) so it remains reachable network-wide.
