World of Computer Networking Your CCNA start - Static Internet Protocol (IP) Addresses

The video tutorial discusses the differences between static and dynamic IP addresses. It explains that static IP addresses are assigned to specific devices and do not change, making them suitable for services like web and email servers. However, they are costly and require additional security measures. Dynamic IP addresses, on the other hand, are more suitable for end-user devices like mobile phones and laptops. The tutorial also covers the advantages and disadvantages of static IPs, including cost and security concerns, and suggests using firewalls to protect servers with static IPs.

What is a key characteristic of a static IP address?

• It changes frequently.

• It is assigned to multiple devices.

• It remains constant for a specific device.

• It is only used for temporary connections.

Why are static IP addresses beneficial for web services?

• They allow permanent access to servers.

• They are cheaper than dynamic IP addresses.

• They are easier to remember than domain names.

• They automatically change to improve security.

How does DNS service enhance the use of static IP addresses?

• By mapping hostnames to IP addresses permanently.

• By encrypting the IP address for security.

• By changing the IP address frequently.

• By providing temporary access to servers.

What is a major disadvantage of using static IP addresses?

• They are less secure than dynamic IP addresses.

• They are more expensive than dynamic IP addresses.

• They cannot be used for web services.

• They are difficult to configure.

What security measure can be taken to protect servers with static IP addresses?

• Using firewalls to block unnecessary connections.

• Disabling DNS services.

• Changing the IP address frequently.

• Assigning multiple IP addresses to a server.
