dns lookups

Umm, cuando en Linux ejecto nslookup, me recomienta el uso de host o dig. ¿Por que?
Investigando un poco me he encontrado con esta Guía de TCPI/IP. La cual tiene una sección sobre nslookup, host y dig: TCP/IP DNS Name Resolution and Information Lookup Utilities (nslookup, host and dig) .

En ella se comenta que en algunos circulos de Unix, se considera a nslookup como 'deprecated', y sus alternativa son host y dig. La primera es la mas sencilla.

Adjunto una parrafada sobre los problemas de nslooup:

"The nslookup utility is widely deployed on both UNIX and Windows systems, but the program is not without its critics. The complaints about it mainly center around its use of non-standard methods of obtaining information, rather than standard resolution routines. I have also read reports that it can produce spurious results in some cases. One example of a significant problem with the command is that it will abort if it is unable to perform reverse lookup of its own IP address. This can cause confusion, because users mistake that error for an error trying to find the name they were looking up.

For this and other reasons, a number of people in UNIX circles consider nslookup to be a “hack” of sorts, and for this reason, in some newer UNIXes nslookup has been deprecated. This simply means that it is still included in the operating system for compatibility, but it is not recommended and may be removed in the future. Instead, a pair of newer utilities are provided: host and dig."
