dns - Recursive name resolution - Message exchange -


i reading recursive name resolution, , understand how works , all. but, wanted know if client queried url this:

http://www.dept.abc.edu/~dept103/

then how messages exchanged? first contacted dns server query iterative query edu dns server first obtain referral abc.edu , on?

what ~dept103? used too?

~dept103 has nothing dns. in instance it's folder name, file, or query string.

if query can not resolved locally, example cache, outside name server contacted.

first root dns server queried, .edu, abc.edu, dept.abc.edu , www.dept.abc.edu.
