How many hosts per subnet

What would be a realistic number of hosts in a 100BaseT network, before you have to start thinking on subnetting further?
Or in another words. How many hosts would you keep in the same broadcast domain?

In a 100BaseT network, with subnet 10.20.20.0/24, I could have 254 hosts as part of the same broadcast domain, would that be considered too many hosts "chatting" among them?

I would like to know what people that maintain networks would recommend.

NAME
ypinit - set up NIS client SYNOPSIS
/usr/sbin/ypinit [-c] [-m] [-s master_server] DESCRIPTION
ypinit can be used to set up an NIS client system. You must be the superuser to run this command. This script need not be used at all if ypbind(1M) is started with the -broadcast option (it is invoked with this option from the svc:/network/nis/client:default service). Normally, ypinit is run only once after installing the system. It may be run whenever a new NIS server is added to the network or an existing one is decommissioned. ypinit prompts for a list of NIS servers to bind the client to; this list should be ordered from the closest to the furthest server. Each of these NIS servers must be listed in either the /etc/hosts or the /etc/inet/ipnodes file along with its IP address. ypinit stores the list in file /var/yp/binding/domain/ypservers. This file is used by ypbind when run without the -broadcast option. OPTIONS
-c Set up a ypclient system. -m Build a master ypserver data base. -s master_server Slave data base. master_server must be the same master configured in the YP maps and returned by the ypwhich -m command. FILES
/etc/hosts /etc/inet/ipnodes /var/yp/binding/domain/ypservers ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWnisu | +-----------------------------+-----------------------------+ SEE ALSO
svcs(1), svcadm(1M), ypbind(1M), sysinfo(2), hosts(4), ipnodes(4), attributes(5), smf(5) NOTES
The NIS client service is managed by the service management facility, smf(5), under the service identifier: svc:/network/nis/client:default Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser- vice's status can be queried using the svcs(1) command. BUGS
ypinit sets up the list of NIS servers only for the current domain on the system when it is run, that is, the domain returned by the SI_SRPC_DOMAIN command to sysinfo(2). Care should be taken to ensure that this is the same as the desired domain for NIS client processes. SunOS 5.10 13 Aug 2004 ypinit(1M)
