Answer:
Network Address Translation (NAT)
Step-by-step explanation:
n sub-netting, a computer called a Network Address Translation (NAT) device converts private IP addresses into normal IP addresses when it forwards packets from those computers to the Internet.
Network Address Translation is a part of firewall security, which assigns public address to computer(s). Rather than using many addresses for each component in a private network, NAT securely and efficiently assigns one address when they need to communicate on internet.
