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!

How can I see the TTL value using nslookup?
I'm not sure how force nslookup to show TTL but the `dig` utility is
far more better tool for getting such information:
I agree, it's not for me though :-)
I have to teach some Windows people about the DNS, and wanted to show
them that they could use 'nslookup' on either the Linux box provided, or
their own Windows PC's. In this instance the TTL is important. So I was
hoping that the MS and BIND nslookup commands would display something
pretty much similar to each other so as not to confuse the people too
much.
As far as I can tell no BIND 9 nslookup command shows the TTL. I am
currently looking at an 8.2.3 version to see if I can patch the 9.5.1
one to display TTL's again. It may, however, be better to introduce them
to dig rather than having to maintain the nslookup command.
Removing features from nslookup gets us that much closer to KILLING and
BURYING it. Forever.
If I had a nickel for every time someone mis-read the output of nslookup
and mistook the nameserver's name, for the name of the server they're
actually looking up, well, let's just say I probably wouldn't be posting
to bind-users from my work account...
(Fortunately nslookup's whole won't do a lookup because I can't
reverse-resolve my resolver bogosity isn't really an issue at Chrysler,
since we maintain proper reverse mappings, but that's another popular
nslookup sucks, don't use it-category posting to this mailing list)

Fortunately (or not - it would be another nail) that bogosity is gone
from recent nslookups.

You can do an ipconfig /displaydns to see some TTL info.
