Sorry, but it is related to several TCP/IP related areas.
First though, there is no specific PHYSICAL limitation to the number of nodes you are allowed. There are obviously practical limitations relating to bandwidth (at some point, usually at your interface to the Internet, all your nodes will be sharing the same bandwidth), equipment (number of available ports on hubs/switches, etc.), and size of area (individual Ethernet connections cannot exceed 100 meters.
From the TCP/IP aspect, you are limited by the number of IP addresses available to you.
If you are using one of the private IP address ranges, you are limited by the class of address being used and the configured subnet mask.
If you are using public IP address, youare limited to the block that has been registered and assigned to your organization.
