IP Addressing with VLSM and EIGRP for 4 Routers with 2 Networks on each in CPT, Subnetting Q?

[Novatian]

Good day, I am doing Cisco Packet Tracer exercises. I have a set of 4 routers, each with 2 lots of hosts attached. My IP Address to begin with is like 172.44.0.0/16 Router one has 2 PC attached, and the first one represents 1 of 200 hosts. The second 100 hosts. Router 2 has one set of 100 and one of 60. Router 3 has 60 and 30, also represented by a PC each in packet tracer. The last Router 14 and 14.

I want to ask about IP addresses, for each host group there is a first such as 172.44.0.1 and a broadcast such as 172.44.0.255. Which gives the subnet mask? What is it?

I have to use VLSM for the IP Addresses.

The task requires EIGRP. How often do I need to use the IP Address and only one or also 172.44.2.223?
How does the input programming go? router eigrp 20 network 172.44.0.0?

Please help me.

Router eigrp 20
network 172.44.0.0

Done

Can you attach a diagram of your network, not quite picturing it.

VLSM is really easy once you get the hang of it.
