IPv4 Address

Network Address

There are two types of network addresses

 Logical Address

  •    IP Address

 Physical Address

  •    MAC Address (48bit)  /Media Access Control

IP =Internet Protocol

Protocol in networking = Set of standard rules to communicate with each other.

There are two versions of  IP

  1. IPv4 (32 bits)
  2. IPv6 (128bits)

So we mainly talk about IPv4. The IPv4 have 32bits. It's separated by 4 octets. One octet has 8 bits.

1 byte = 8 bits
32 bits = 4 bytes

Octet  Lowest value in binary = 00000000    Octet  Lowest value in decimal = 0
Octet  Highest value in binary = 11111111     Octet  Highest value in binary = 255

How that's 255 comes in decimal value?


Then, the octet range in decimal 0-255

Seedr - The fastest way to download Torrents

  Hi guys. Today, I am going to talk about a special website. Its name is seedr. For entertainment, we are using it to download lot of torrent files like movies, tv-series, games, etc. But there are have some issues. When we download a torrent, its download speed depends on the seeders and leechers. sometimes we have to wait for hours. But if you are trying to use the seedr website, you don't have to wait for a long times for downloads. This website is downloading our files super-fast. So that's awesome. You can paste the magnet link in the top of the text box in the seedr website and click the plus button. After a little time, your file is ready to download. The registration is also very easy. After the registration, you will get free 2 GB capacity to download unlimited times. You can freely increase some capacity doing some little activities. Those are mentioned in the seedr website. By the way, if you want more capacity, for some reason you can choose a subscription option a

Subnet ID

If any requirement to subnet some network, we must need the subnet id. Subnet id use for identity which subnet in the network. we get an example scenario here. There is an ABC company. That company have 4 divisions.  So that network wants 4 subnets. but how to apply subnets to the computer. It`s also doing by bits. 1 bit have 0 and 1. So there are two IDs . In this scenario, we want 4 subnets. Then we want 4 IDs. since we need 2 bits  1 bit =0, 1 2 bit = 00, 01, 10, 11 how to include subnet id into the IP address. if we get a class c address as 192.168.10.4, this IP network id can not change, only the host id can change. So we book some bits for subnet id from that host id. Subnet      Subnet ID   (2 bit) D1             00 D2             01 D3             11 D4             10 D1 (00) 192.168.10.00 000000  (192.168.10.0) Network Address 192.168.10.00 000001  (192.168.10.1) 192.168.10.00 000010  (192.168.10.2)                  | 192.168.10.00 111111   (192.168.10.63) Broadcast Address
