# How do you convert an IP address to a decimal?

## How do you convert an IP address to a decimal?

The computer views the IP addresses as binary code, so to convert the code to decimal format, a mathematical equation must be used. Convert the binary to decimal by placing a value of 0 on all the 0 bits in the number. 1s get a value of 2 to the power of the bit’s location.

**What is binary to decimal IP address?**

In binary notation, all four octets are written in binary format. In decimal notation, all four octets are written in decimal format. A decimal equivalent value of the bits is used in each octet….Converting decimal number in binary number.

Operation | In Decimal | In Binary |
---|---|---|

Skip | Skip position value | Set bit to 0 |

### How do you convert binary notation to dotted-decimal notation?

In the dotted-decimal notation, periods are used to divide the four octets. In the binary notation, spaces are used to separate the four octets. If you want to convert a binary number to a decimal number, add the value of each bit position set to 1.

**How do you write a subnet mask in binary?**

For example, to write the IPv4 address 192.168. 42.23 with a subnet mask of 255.255. 255.0 in slash notation: Convert the subnet mask to binary….IPv4.

Network Mask | Slash Equivalent |
---|---|

255.255.255.248 | /29 |

255.255.255.252 | /30 |

255.255.255.254 | /31 |

255.255.255.255 | /32 |

## How do I find the subnet mask of an IP address?

- In the Windows search fields, type cmd, to open command prompt.
- Press Enter.
- Type ipconfig/all press Enter.
- Find your network settings.
- Your PC’s IP address and your network Subnet Mask and Gateway will be listed.

**How do you convert binary subnet mask to decimal?**

To convert a binary subnet mask to dotted decimal notation, follow these steps:

- Divide the subnet mask into octets by writing the 32-bit binary subnet mask with periods inserted at the octet boundaries: 11111111.11111111.11110000.00000000.
- For every all-ones octet, write down 255.

### What is the subnet mask 255.255 255.0 in binary?

11111111.11111111

Convert the subnet mask to binary. In this example, the binary representation of 255.255. 255.0 is: 11111111.11111111.
