NO.73 How many usable IP addresses are there in a 20-bit subnet?

NO.74 You have a DHCP server on your MikroTik router. The IP addresses 10.1.2.2-10.2.2.20 are distributed in the DHCP network. Additionally, 3 static IP address are defined for your servers: 10.1.2.31-10.1.2.33.
After a while 20 more IP addresses need to be distributed in the network. It is possible to distribute the extra IP address without adding another DHCP Server:

ICMP can provide hosts with information about network problems.
ICMP is encapsulated within IP datagrams.
ICMP is encapsulated within UDP datagrams.
