I have a project ,in this project i need a Global-scale Mapping System,so the first step i just nedd to build small-private DNS-based enviroment,and achieve my goal. in order to accomplish these i need to adding a new RR(eg. mapping_RR) and creat a new domain(which maintain the mapping info,and the type of mapping info is mapping_RR). Now here is design,client-program send a mapping request,resolver can tell the request type ,and send to proper domain-nameserver and send reply back.
yestoday, i have check lib\dns\rdata\in_1\aaaa_28.c,but i don't know the whole project will work if i just imitate aaaa_28.c to write a mapping_RR.c . if it doesn't work ,please direct me with some papers or Independent Code. thanks! 2009/10/16 <bind-users-requ...@lists.isc.org> > Send bind-users mailing list submissions to > bind-users@lists.isc.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.isc.org/mailman/listinfo/bind-users > or, via email, send a message with subject or body 'help' to > bind-users-requ...@lists.isc.org > > You can reach the person managing the list at > bind-users-ow...@lists.isc.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of bind-users digest..." > > > Today's Topics: > > 1.
