Question: What Is IP Address And Subnet Mask?

What is the difference between subnet and subnet mask?

A subnet denotes a range of addresses that can be allocated to hosts, such as 192.168.

The subnet mask is the classical way of representing which bits are part of the network portion of the address vs.

the host bits of the address.

The subnet mask for a /24 network is 255.255..

What is a 16 subnet?

The last three octets of a Class A subnet mask are used to address hosts on a LAN; the 24 bits you can manipulate however you wish. … It saves you from typing, or pronouncing, the whole mask. For example, /8 means 255.0. 0.0, /16 is 255.255. 0.0, and /24 is 255.255.

What are the 4 parts of an IP address?

IP Address ComponentsAddress Class. Early in the development of IP, the IANA (Internet Assigned Numbers Authority) designated five classes of IP address: A, B, C, D, and E. … Default Subnet Mask. … The Network Field. … The Host Field. … Non-default Masks. … The Subnet Field.

What is IP and subnet mask?

A subnet mask is a 32- or 128-bit number that segments an existing IP address in a TCP/IP network. It is used by the TCP/IP protocol to determine whether a host is on the local subnet or on a remote network. … Once given the IP address and its subnet mask, the network address (subnet) of a host can be determined.

What does IP subnet mean?

A subnetwork or subnet is a logical subdivision of an IP network. … This results in the logical division of an IP address into two fields: the network number or routing prefix and the rest field or host identifier. The rest field is an identifier for a specific host or network interface.

What does it mean 192.168 0.0 24?

192.168.0.0 Refers to the IP adress /24 refers to the subnet. / 24 subnet is 255.255.255.0. 192.168.0.0/24 is common for home networks.

How does subnet mask work?

A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs. To better understand how IP addresses and subnet masks work, look at an IP (Internet Protocol) address and see how it is organized.

What is a custom subnet mask?

The custom subnet mask, also called a variable length subnet mask, is used to identify the bits used for a network address versus the bits used for a host address. ■ Custom subnet masks are used when subnetting or supernetting.

What is subnet simple words?

A subnet, or subnetwork, is a segmented piece of a larger network. More specifically, subnets are a logical partition of an IP network into multiple, smaller network segments. … One goal of a subnet is to split a large network into a grouping of smaller, interconnected networks to help minimize traffic.

Why do we need subnet mask?

9 Answers. We need a subnet mask for IPv4 addresses because the address doesn’t give any information on the network size. Class sizes are not the network sizes. … Also to be clear the purpose of the subnet mask is to determine which hosts are on the local network and which are outside of the network.

What do I put for subnet mask?

Most home networks use the default subnet mask of 255.255. 255.0. However, an office network may be configured with a different subnet mask such as 255.255. 255.192, which limits the number of IP addresses to 64.

What is a 192.168 IP address?

192.168. 1.1 is a common factory IP address for a consumer-grade router. If the router is used for connecting to the Internet then all computers and devices which access the Internet through it will use this address as their default gateway.

How do I know if my IP is public or private?

Public IP address are the IP addresses which have to registered before use. IANA is responsible for register these IP addresses to the organizations. Private IP address are the IP addresses which are reserved by IANA and they are not routable in the internet. These addresses will be not assigned to any organizations.

How do I make my IP private?

What is my phone’s IP address? Navigate to Settings > About device > Status then scroll down. There, you’ll be able to see your Android phone’s public IP address along with other information such as MAC address.

How can I see my IP address?

On an Android smartphone or tablet: Settings > Wireless & Networks (or “Network & Internet” on Pixel devices) > select the WiFi network that you’re connected to > Your IP address is displayed alongside other network information.

Which of the following is the best definition of IP spoofing?

IP spoofing is the creation of Internet Protocol (IP) packets which have a modified source address in order to either hide the identity of the sender, to impersonate another computer system, or both.

What are the 3 classes of subnet mask?

The three default subnet masks are 255.0. 0.0 for Class A, 255.255. 0.0 for class B, and 255.255. 255.0 for Class C.
