o FAMILY, 2 octets, indicates the family of the address contained in the option, using address family codes as assigned by IANA in Address Family Numbers [Address_Family_Numbers]. o SOURCE PREFIX-LENGTH, an unsigned octet representing the leftmost number of significant bits of ADDRESS to be used for the lookup. In responses, it mirrors the same value as in the queries. o SCOPE PREFIX-LENGTH, an unsigned octet representing the leftmost number of significant bits of ADDRESS that the response covers. In queries, it MUST be set to 0. o ADDRESS, variable number of octets, contains either an IPv4 or IPv6 address, depending on FAMILY, which MUST be truncated to the number of bits indicated by the SOURCE PREFIX-LENGTH field, padding with 0 bits to pad to the end of the last octet needed. o A server receiving an ECS option that uses either too few or too many ADDRESS octets, or that has non-zero ADDRESS bits set beyond SOURCE PREFIX-LENGTH, SHOULD return FORMERR to reject the packet, as a signal to the software developer making the request to fix their implementation.
