e DNS authoritative name server. Once this mapping is changed in the authoritative name server, will all future references in the Internet to www.uga.edu then be sent to 128.192.224.40?

Answer:

NO

Explanation:

All future references in the internet to "www.uga.edu" will not be sent to "128.192.224.40" because, Local Domain Name System (DNS) caches throughout the internet will not timeout the old mapping of “www.uga.edu” to “128.192.225.20” until the interval associated with that mapping times out. Until then the local Domain Name System (DNS) caches won’t query into the system for “www.uga.edu” and would not learn the new mapping.
