Brian My exposure to zoneids started with the installation of Windows 2000 Servers, but there was no SNMP involved there; I cannot recall if URI were in use, I think not, and the ids I saw were, I think, numeric. I did see that RFC4007 says that " Implementations choosing to follow the recommended basic API [10] will want to restrict their index values to those that can be represented by the sin6_scope_id field of the sockaddr_in6 structure." but I am not sure what that means, in terms of character set.
