As a result, DNS Cookies are impractical to deploy on multi-vendor anycast networks, because the Server Cookie constructed by one implementation cannot be validated by another. This document provides precise directions for creating Server Cookies to address this issue. Furthermore, {[}FNV{]} is obsoleted as a suitable Hash function for calculating DNS Cookies. {[}SipHash-2.4{]} is introduced as a new REQUIRED Hash function for calculating DNS Cookies. This document updates {[}RFC7873{]}}, }
