Dear Aftab, Chris and esteemed colleagues, I appreciate the insights shared by all.
I recognize the existence of various upper-layer identification schemes, such as OID, Handle, and Ecode, and I do not aim to replace them with IPv6 addresses. Our approach is complementary to these systems. Typically, Internet users have the option to access a host either through a domain name or an A/AAA record IP address. In a similar vein, we've enabled our team to access product item information by utilizing an IPv6 address. For example, this address could be derived from a hash mapping of an OID into a 128-bit address space. The initiative stems from a local business customer's requirement. My team has managed to generate millions of IPv6 addresses within the customer's legitimate /32 prefix range. The strategy involves: - Utilizing a same /64 routing prefix differentiated by unique /64 interface suffixes, which are the result of hashing product codes. - Employing a same /32 routing prefix, with distinct /32-64 subnet IDs and /64-128 interface suffixes, also derived from hashed product identifiers. The customer has leveraged these IPv6 addresses to create corresponding QR codes in URL format, such as `http://[1234:5678::90AB]`. This ensures a one-to-one correspondence between an item, its product code, and its IPv6 address. This implementation has helped the customer significantly improved product traceability and anti-counterfeiting measures. I am keen on presenting the details of our practice at the APNIC meeting, seeking a more in-depth exchange with experts like you.
