Extracting solicitor's relayed peer-address, using EUI-64 for lease IID.

[Paul Duffy (paduffy)]

Greetings from a very large IPv6 IoT deployment which is using DHCPv6 for address assignments.

The technology requires field devices form their link-local IPv6 address with interface identifier being the modified EUI-64 format described in RFC 4291.  The solicitor's link-local IPv6 address will be contained in the peer-address field relayed to the DHCPv6 service.

Is ISC able to extract the EUI-64 from the peer-address link-local and use that as the IID for an address lease to the soliciting device?

Thanks in advance.
