This means the local network is using a Class B Network address scheme. Anytime you see an IP of 172.16.x.x - 172.31.x.x you are using a class B address. This means the first 2 octates of 172.16 - 31 are what defines the local network, and anything in the last two octates defines the host (ie computers) actual IP address assignment.
Class A
Yes Cisco IOS IP address has a secondary address that allows the network interface to communicate to hosts in different IP sub nets. It allows you to have unlimited number of secondary addresses.
15.242.55.6227 is an invalid IP address.
Yes, if the connection is direct (not through NAT, for example) then each device would need a separate public IP address.
There is no program to change your ip address. Your ip address is given to you by your internet service provider.
IP-based virtual hosts use the IP address of the connection to determine the correct virtual host to serve. Therefore you need to have a separate IP address for each host. With name-based virtual hosting, the server relies on the client to report the hostname as part of the HTTP headers. Using this technique, many different hosts can share the same IP address

•If the hosts on a network using private IP addresses need to access the Internet, a problem arises because the private IP addresses are not allowed on the Internet. •The solution is to use NAT (Network Address Translation), which uses a single public IP address to access the Internet on behalf of all hosts on the network using other IP addresses.
NAT - Network Address Translation.
Any computer which is connected to network and has unique ip address for the network.
IP address and host name
The number of possible IP address decreases as one steps down from Class A to Class C IP addresses because the availability of usable hosts. There is a decrease in the number of usable hosts from Class A to Class C IP addresses.
