DHCP lease process

A DHCP client enabled PC must obtain a lease for an IP address from a DHCP server.

Before the lease expires, the DHCP server must renew the lease for the client or client must obtain a new lease.

Lease Renewal

The renewal process occurs when the client already has a lease and needs to renew that lease with the server.

Network Address Translation (NAT)

Network Address Translation (NAT) is the process where a network device, usually a firewall, assigns a public address to a computer (or group of computers) inside a private network. 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.

1) Static NAT (Network Address Translation) - Static NAT (Network Address Translation) is one-to-one mapping of a private IP address to a public IP address. Static NAT (Network Address Translation) is useful when a network device inside a private network needs to be accessible from internet.

2) Dynamic NAT:- can be defined as mapping of a private IP address to a public IP address from a group of public IP addresses called as NAT pool. Dynamic NAT establishes a one-to-one mapping between a private IP address to a public IP address. Here the public IP address is taken from the pool of IP addresses configured on the end NAT router. The public to private mapping may vary based on the available public IP address in NAT pool.

3) PAT (Port Address Translation) - Port Address Translation (PAT) is another type of dynamic NAT which can map multiple private IP address to a single public IP address technology known as Port Address Translation.

Questions:-

• What are the types of NAT
• Which is the most preferable NAT?
• Different between Static, Dynamic, PAT NAT

Simple Past Tenses:-

With most verbs the past tense is formed by adding -ed:

call >> called; like >> liked; want >> wanted; work >> worked

But there are a lot of irregular past tenses in English.

Use:-

We use the past tense to talk about:

• something that happened once in the past:

I met my wife in 1983.
We went to Spain for our holidays.
They got home very late last night.

• something that happened again and again in the past:

When I was a boy I walked a mile to school every day.
We swam a lot while we were on holiday.
They always enjoyed visiting their friends.

• something that was true for some time in the past:

I lived abroad for ten years.
He enjoyed being a student.
She played a lot of tennis when she was younger.

• we often use phrases with ago with the past tense:

I met my wife a long time ago.
Questions and negative:-

We use did to make questions with the past tense:

When did you meet your wife?
Where did you go for your holidays?
Did she play tennis when she was younger?
Did you live abroad?

Fill in the blank using was/ware.

1. I was in Canberra last spring.

Network Address Translation (NAT) is the process where a network device, usually a firewall, assigns a public address to a computer (or group of computers) inside a private network. 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, 172.16.0.0 to 172.31.255.255, or 192.168.0 0 to 192.168.255.255). The private addressing scheme works well for computers that only have to access resources inside the network, like workstations needing access to file servers and printers. Routers inside the private network can route traffic between private addresses with no trouble. However, to access resources outside the network, like the Internet, these computers have to have a public address in order for responses to their requests to return to them. This is where NAT comes into play.

Type of NAT:-

1) Static NAT--With this type of NAT, a NAT router maintains a table that associates each internal IP address with a corresponding external allocated (i.e., registered) Internet IP address. With static NAT, you must register an IP address for every machine that connects to the Internet. This approach isn't used very often because it doesn't save on registering IP addresses. However, static NAT can be useful for making devices accessible from the Internet--the external IP address will always point to the internal address stored on the NAT router.

Questions:-

1) What is NAT
2) Types of NAT

3) On which Cisco routing hardware is Cisco IOS NAT available? How can the hardware be ordered?
