On RENEW, it is allowed to remove the old IPv6 address and add a new one:
https://tools.ietf.org/html/rfc3315#section-18.1.318.1.3. Creation and Transmission of Renew Messages
"The server may also add new addresses to the IA. "
"The server may remove addresses from the IA by setting the preferred and valid lifetimes of those addresses to zero."
When will server do this? After an outage?

Dusan.

If the renewal failed, at the end of the lease, the client > device should send a solicit message which could result in a new address (or the same address the client had > before). I don't think the client can get a new (different?) address during renewal?
