How to calculate subnet mask manually without IP Calculator?
To calculate the subnet mask, we should first understand the decimal conversion to binary and binary to decimal.

CONVERTING DECIMAL TO BINARY.

Sample Question : (Decimal)156 = what is binary?
Answer:
For easy, we recommend using paper and pen to count them.

Binary is a 2-based number, so to calculate it, the decimal number is also bound to divide by two.


Biner adalah bilangan berbasis 2, jadi untuk menghitungnya, bilangan desimal juga terikat untuk dibagi dua.

When the number being divided is an even number then the remainder is 0, and when the number being divided is an odd number then the remainder is 1.


ketika bilangan yang dibagi adalah bilangan genap maka sisanya adalah 0, dan ketika bilangan yang dibagi adalah bilangan ganjil maka sisanya adalah 1.

Continue down, divide each new share by two and write the rest to the right of each number that is shared. Stop when the result is zero


Teruskan menurun, membagi setiap hasil bagi yang baru dengan dua dan menulis sisa di sebelah kanan dari setiap bilangan yang dibagi. Berhentilah ketika hasil baginya nol.

Write the new binary number. Start from the bottom left digit, read the remaining sequence ascending to the top. In this example, you should get 10011100 results. This is the equivalent binary number of the decimal number 156.


Tulislah bilangan biner baru tersebut. Mulailah dari angka sisa paling bawah, bacalah urutan sisa secara menaik menuju paling atas. Dalam contoh ini, Anda seharusnya mendapatkan hasil 10011100. Ini adalah bilangan biner ekuivalen dari bilangan desimal 156. Atau jika ditulis dengan subskrip basis angkanya.

CONVERTING BINARY TO DECIMAL

Sample Question : (Binary) 10011011 = What is Decimal?

Write the binary number and the list of squares 2 from right to left. Then write the square 2 from right to left. Start from 20, ie 1. Increase squares one by one. Stop if the number of numbers on the list is the same as the number of binary digits. The example number, 10011011, has eight digits, so the list has 8 numbers, like this: 128, 64, 32, 16, 8, 4, 2, 1.


Tuliskan angka biner dan daftar kuadrat 2 dari kanan ke kiri. Kemudian tuliskan kuadrat 2 dari kanan ke kiri. Mulailah dari 20, yaitu 1. Kenaikan kuadrat satu per satu. Hentikan jika jumlah angka yang ada di daftar sama dengan banyaknya digit angka biner. Contoh angkanya, 10011011, memiliki delapan digit, jadi daftarnya memiliki 8 angka, seperti ini: 128, 64, 32, 16, 8, 4, 2, 1.

Write the binary digit number under the list of the two squares. Write the number 10011011 below the numbers 128, 64, 32, 16, 8, 4, 2, and 1 so that each binary digit has the square of both numbers respectively. The number 1 to the right of the binary number is parallel to the 1 in the second and second squares. You can also write a binary digit above the list of squares of two, if you prefer it. The important thing is you can pair it.


Tuliskan digit angka biner di bawah daftar kuadrat dua. Tuliskan angka 10011011 di bawah angka 128, 64, 32, 16, 8, 4, 2, dan 1 sehingga setiap digit biner memiliki kuadrat angka duanya masing-masing. Angka 1 di kanan angka biner sejajar dengan angka 1 dalam daftar kuadrat 2 dan selanjutnya. Anda juga bisa menuliskan digit biner di atas daftar kuadrat dua, jika Anda lebih memilihnya. Yang penting adalah Anda bisa memasangkannya.

Drain the final value of each of the two squares. Combit each digit of binary numbers. If the digit is 1, write the squares of the two pairs below the 1. If the digit is 0, write 0 below 0. Then add all the numbers written below the binary digits digits


Tuliskan nilai akhir setiap kuadrat dua. Sisirlah setiap digit angka biner. Jika digitnya adalah 1, tulislah kuadrat dua pasangannya di bawah angka 1 tersebut. Jika digitnya adalah 0, tulislah 0 di bawah angka 0. lalu tambahkan semua angka yang tertulis di bawah digit angka biner

Write your answer with a subscript of the base.


Tulislah jawaban Anda dengan subskrip basisnya.
