## Can you have 256 in an IP address?

As a reference, with 8 bits (each part between dots), you can have 256 different values (from 00000000=0 to 11111111=255). For example, an IP address would be 192.228. 17.57 ( in bits 11000000 11100100 00010001 00111001), representing a C kind address.

**Can an IP address be over 255?**

So, the full IP addressing range goes from 0.0. 0.0 to 255.255. 255.255. The reason each number can only reach up to 255 is that each of the numbers is really an eight digit binary number (sometimes called an octet).

### How many total IP can get when I use 255.255 255.224 as the subnet mask in the IP?

A /27 (255.255. 255.224) is 3 bits on and 5 bits off. This provides 8 subnets, each with 30 hosts….Exercise :: Subnetting – Subnetting.

A. | 255.255.255.192 |
---|---|

D. | 255.255.255.248 |

**Where does 256 come from in subnetting?**

255.0 we have 8 bits left, and with 8 bits the highest “number” we can create is 256. 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255. Don’t forget about the 0! The 0 is being used so the highest value you can create is 256.

#### How can I use more than 254 IP address?

If more than 254 IP addresses are needed on a network then multiple subnets should be used with routers and maybe VLANs. You could spilt different departments or building on different subnets.

**How can I get more than 254 IP address?**

Re: DHCP with more than 254 addresses All you have to do is turn on DHCP for that VLAN holding the 700 computers. If you’re using /24 subnet, then you can only have 253 addresses (one is the MX and the other two unusable by hosts).

## How many usable hosts can we get when I use 255.255 255.252 as the subnet mask in the IP?

Quick Hits: IP Networking Chart

Network Bits | Subnet Mask | Number of Hosts |
---|---|---|

/27 | 255.255.255.224 | 30 |

/28 | 255.255.255.240 | 14 |

/29 | 255.255.255.248 | 6 |

/30 | 255.255.255.252 | 2 |

**How many host addresses can be assigned with a subnet mask of 255.255 255.0 explain how you calculated the result?**

Mask 255.255. 255.0 has 16 bits for the subnet and 8 bits of the host. Have possible 28 -2 hosts =254 which is enough.

### How do I convert an IP address to base 10?

To convert an IP address to base 10, use the following: w * 16,777,216 + x * 65,536 + y * 256 + z = Decimal IP Address

**How do I calculate my IP range?**

Fortunately for you, Colocation America has your back with our IP range calculator suitable for all ages! Just plug in your IP range to figure out your subnet mask, IPv4/6 range, and the amount of usable IPs. Now, let’s get into the nitty-gritty. The calculator is useful because it does the work for you.

#### What information does this calculator return about IPv4 and IPv6 subnets?

This calculator returns a variety of information regarding Internet Protocol version 4 (IPv4) and IPv6 subnets including possible network addresses, usable host ranges, subnet mask, and IP class, among others.

**How do I find the octet of a subnet with base 256?**

Add that Base-256 dotted-decimal equivalent to the 1st subnet, to get the IP address of the target subnet. Evaluate the number: If the decimal number is >= 256, then continue to step 2. If the decimal number is less than 256, then use that decimal number for the octet.
