On nslookup, in particular, the program has some ambiguous behavior and can be problematic when trying to debug certain DNS issues. Dig was developed to be a reliable replacement that has predictable behavior at all times. There is a companion to dig called "host" that is a simple lookup, including looking up in-addr.arpa entries ("host 8.8.8.8"). In most cases, you will get more consistent results by using dig and host, which is why nslookup is deprecated.
