Question

"An ISP has issues a company the following Global Unicast Address:

....What might an example network ID look like after subnetting?"

Answer 1

Subnetting a Global Unicast Address results in dividing the IP range into sub-networks, each with a unique network ID. For example, if the main address is 2001:0db8:85a3::/48, a subnetted network ID may look like 2001:0db8:85a3:0001::/64.

Step-by-step explanation:

When an Internet Service Provider (ISP) issues a Global Unicast Address to a company, and the company decides to implement subnetting, they divide the provided IP address range into smaller, more manageable sub-networks. To better illustrate this, let's take an example where a company receives an IPv6 Global Unicast Address such as 2001:0db8:85a3::/48. After subnetting, one possible network ID could be 2001:0db8:85a3:0001::/64, where '0001' represents a specific subnet identifier within the company's network.

Each subnet has a unique identifier to ensure network packets are routed correctly. Therefore, an organization can have multiple subnets like 2001:0db8:85a3:0002::/64, 2001:0db8:85a3:0003::/64, and so on, each with a distinct subnet part of the IP address, allowing more efficient network management and security.
