Why would you use dynamic NAT?

Use dynamic NAT to translate a set of unregistered IP addresses to a smaller set of registered addresses. Dynamic NAT enables you to connect to a large number of hosts to the public Internet using a limited number of registered addresses.

What are the situations where NAT is required?

The main use of NAT is to limit the number of public IP addresses an organization or company must use, for both economy and security purposes. The most common form of network translation involves a large private network using addresses in a private range (10.0. 0.0 to 10.255. 255.255, 172.16.

What is Dynamic NAT overload?

Key Concept – NAT Overload is a special form of dynamic NAT that allows many-to-one mapping of local addresses to a smaller number global addresses from a pool of global addresses. The pool of global addresses may even consist of a single address. NAT Overload is also called Port Address Translation (PAT).

What are some advantages of NAT choose all that apply?

Some benefits of NAT include:

• Reuse of private IP addresses.
• Enhancing security for private networks by keeping internal addressing private from the external network.
• Connecting a large number of hosts to the global Internet using a smaller number of public (external) IP address, thereby conserving IP address space.

What is static NAT and Dynamic NAT?

While static NAT is a constant mapping between inside local and global addresses, dynamic network address translation allows you to automatically map inside local and global addresses (which are usually public IP addresses). Dynamic NAT uses a group or pool of public IPv4 addresses for translation.

Which statement accurately describe dynamic NAT?

Which statement accurately describes dynamic NAT? It provides an automated mapping of inside local to inside global IP addresses.

What are the three types of NAT and where would each one be used?

There are 3 types of NAT:

• Static NAT – In this, a single private IP address is mapped with a single Public IP address, i.e., a private IP address is translated to a public IP address.
• Dynamic NAT –
• Port Address Translation (PAT) –

How does NAT overload work?

In NAT Overloading, when a computer from a inside network (configured with a Private IPv4 address) communicate to another computer in the internet, the NAT Device (Router) changes the source port number (TCP or UDP) with another port number. These TCP or UDP port mappings are kept in a table in Router memory.

What is the major benefit of using NAT overload?

It allows many internal hosts to share the same public IPv4 address. It improves network performance for real-time protocols.
