Could you be more specific about it? It may be a minority implementation, but I thought traditional stub resolver implementations in BSD variants systems (getaddrinfo/gethostbyname with the backend of libresolv) didn't hardocde special logic for "localhost." yet. It's true that such implementations refer to /etc/hosts and it has system-installed mapping between 'localhost.' and ::1 by default. Do you mean (in addition to hardcoding the special logic) this kind of combination of generic implementation with default system configuration? I'm asking this because I think the difference between this and hardcoded implementation can matter in the context of this draft. -- JINMEI, Tatuya _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
