Lets relate it to hose pipes. Shared IP is like you are using one hose that is shared to a number of flats. Exclusive IP is like your flat having its own hose pipe.
I use shared and exclusive. In the global zone Ive created an aggregated link ( joined a number of nics together to make a really fast NIC, or `pipe`) On a number of training zones, Ive then used this NIC as a SHARED IP, i.e. that the 5 training zones using that pipe, each having a virtual ip configured using the underlying pipe.
On a production zone, where I want more control of the NIC, Ive created the production zone using exclusive NIC. Within the zone configuration file ( zonecfg ) I just tell it that Im using the exxclusive-ip and tell it what nic the zone will have.
Exclusive-IP allows for greater control over the NIC, SHared-IP doesnt, as the Global zone controls the underlying hardware. When it comes to zones and hardware, zones dont have truely 100% control over it. ITs like a client PC using a proxy server to surf the web. On the surface it looks like your internet request surfs the net, but infact its your proxy server that is doing it. So, sometimes the application, zone, needs more control over its NIC, if you are using clustering software, IPMP etc etc, so you use the EXclusive-IP in this situation.
Sorry if my explanation is a bit over the place :-)

zprint
ZPRINT(1) General Commands Manual ZPRINT(1)
NAME
zprint - show information about kernel zones
SYNOPSIS
zprint [-w] [-s] [-c] [-h] [name]
DESCRIPTION
zprint(1) displays data about Mach zones. By default, zprint will print out information about all Mach zones. If the optional name is
specified, zprint will print information about each zone for which name is a substring of the zone's name.
zprint interprets the following options:
-w For each zone, zprint calculates how much space is allocated but not currently in use, the space wasted by the zone.
-s zprint sorts the zones, showing the wasting the most memory first.
-c (Default) zprint prints zone info in columns. Long zone names are truncated with '$', and spaces are replaced with '.', to allow
for sorting by column. Pageable and collectible zones are shown with 'P' and 'C' on the far right. Zones with preposterously large
maximum sizes are shown with '----' in the max size and max num elts fields.
-h (Default) Shows headings for the columns printed with the -c option. It may be useful to override this option when sorting by col-
umn.
Any option (including default options) can be overridden by specifying the option in upper-case; for example, -C overrides the (default)
option -c.
