What does 24 mean in IP address?
This means that this IP address is in the subnet = 192.168.
1.0 with subnet mask = 255.255.
Shorthand (AKA CIDR, Classless Inter-Domain Routing), this can be written 192.168.
1.0 /24 where the ‘/24’ represents the number of subnetwork bits active in the mask..

Why do we use loopback address?
A loopback address is primarily used as a means to validate that the locally connected physical network card is working properly and the TCP/IP stack installed. Typically, a data packet sent on a loopback address, never leaves the host system and is sent back to the source application.
What is a broadcast address used for?
What is the broadcast address in terms of Ethernet network. A broadcast address is an IP address that is used to target all systems on a specific subnet network instead of single hosts. In other words broadcast address allows information to be sent to all machines on a given subnet rather than to a specific machine.
What is a 255.255 subnet?
A subnet mask of 255.255. 255.0 allows for close to 256 unique hosts within the network (since not all 256 IP addresses can be used). … 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.
What does 255.255 255.0 tell a router?
A subnet mask is used to tell the network devices (whether it be the computer or any routers, modems, etc.) … 1.104, and its subnet mask is 255.255. 255.0, then the computer (and every other device attached to the same network) will assume that every IP on that computer’s local network will be in the format 192.168.
What type of address is FF FF FF FF FF FF?
Broadcast is possible also on the underlying data link layer in Ethernet networks. Frames are addressed to reach every computer on a given LAN segment if they are addressed to MAC address FF:FF:FF:FF:FF:FF. Ethernet frames that contain IP broadcast packages are usually sent to this address.
Is 255.255 255.255 IP address valid?
No 255.255. 255.255 can’t be allocated to a host, because it is used as limited broadcast address(destination) i.e. when any host wants to broadcast information to all the hosts in its entire network it will assign the destination ip as 255.255. 255.255(ie send to all).
What does IP address 0.0 0.0 mean?
From Wikipedia, the free encyclopedia. In the Internet Protocol Version 4, the address 0.0. 0.0 is a non-routable meta-address used to designate an invalid, unknown or non-applicable target. This address is assigned specific meanings in a number of contexts, such as on clients or on servers.
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.
How many subnets are in a 23?

What is the 127.0 0.1 IP address and what is it used for?
127.0. 0.1 is the loopback Internet protocol (IP) address also referred to as the localhost. The address is used to establish an IP connection to the same machine or computer being used by the end-user.
Is subnet mask always 255?
The zero in the subnet mask will correspond to the xxx of your IP address. If you need more than 255 different addresses, you’ll have to change the DHCP IP’s to 10.0. … xxx (broadcast IP of 10.0. 255.255) and the subnet mask to 255.255.
Why 0 and 127 are not used in IP address?
The class A network number 127 is assigned the “loopback” function, that is, a datagram sent by a higher level protocol to a network 127 address should loop back inside the host. … As 0 was used for pointing to a specific host, 127 was left for loopback.
What is FFFF FFFF MAC address?
The broadcast MAC address is an address where all positions are set to F (FFFF:FFFF:FFFF). RARP is used to find the IP address when the MAC address is already known.
Why is 192.168 always used?
Long story short, we are using 192.168. X.X IP addresses because this is best practice. The IETF has created three IP ranges for private networks, with Class C being the smallest and easiest to control and maintain. This is why most routers use exactly this IP range.
What is IP loopback address?
A loopback address is a special IP address, 127.0. 0.1, reserved by InterNIC for use in testing network cards. This IP address corresponds to the software loopback interface of the network card, which does not have hardware associated with it, and does not require a physical connection to a network.
What is 192.168 called?
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.
