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\_28.c,but i don't know the
whole project will work if i just imitate _28.c to write a
mapping_RR.c . if it doesn't work ,please direct me with some papers or
Independent Code. thanks!
