- extract each parts ip_array=ip.match(/(\d+)\.(\d+)\.(\d+)\.(\d+)\/(\d+)/) //js regex.
- convert to number ip_num = (ip[1]<<24)+(ip[2]<<16)+(ip[3]<<8)+(+ip[4]) //# 0x08080800.
- mask=(1<<(32-ip[5]))-1 //# 0xFF.
- ip_num | mask will be 0x080808FF which is 8.8.8.255.
What is at the end of an IP address?
It indicates the subnet mask of the IP. IP has 32 bits, and number after the slash tells you where does the network part end, host part starts. and /24 says that first 24 bits are used for network designation, while last 8 bits are used for various hosts inside that network.
What is the first and last IP address?
Internet Corporation for Assigned Names and Numbers is responsible for assigning IP addresses. When calculating hosts' IP addresses, 2 IP addresses are decreased because they cannot be assigned to hosts, i.e. the first IP of a network is network number and the last IP is reserved for Broadcast IP.

Do all IPS start with 192?
1 Answer. Show activity on this post. That an IP address starts with 192 doesn't necessarily mean it's a private IP address. For example the ISP Surfnet in The Netherlands assigns IP addresses starting with 192.87, which are perfectly valid Internet addresses (see RIPE Whois database).

What does 24 mean at the end of an IP address?
This is called “slash notation”. There is a total of 32 bits in IPv4 address space. For example, if a network has the address “192.0. 2.0/24”, the number “24” refers to how many bits are contained in the network. From this, the number of bits left for address space can be calculated.
Can an IP address end with 255?
Yes, an IPv4 address can end in 255 without being a broadcast address. For it to be a broadcast address, all bits in the host part need to be ones. In your example, the 32-17 = 15 rightmost bits need to be all ones, not only the rightmost eight. For example, 10.0.
What DHCP range should I use?
Since the default DHCP address range is between 100 and 149, you'll want to avoid all of the addresses between 192.168. 1.100 and 192.168. 1.149 when you're assigning static IP addresses. That leaves the ranges from 2-99 and from 150-254 wide open, which is usually plenty for most home networks.

What does IP address 10.0 0.0 24 mean?
0.0/24 is an invalid subnet. The first valid subnet within the 10.0. 0.0/8 (Class A) network, now sliced with a /24 subnet mask is... 10.0. 1.0/24 .
What are the 3 types of addresses in a network?
Some link-layer protocols define three types of addresses: unicast, multicast, and broadcast.
What is IP address example?
An IP address has two parts: the network ID, comprising the first three numbers of the address, and a host ID, the fourth number in the address. So on your home network — 192.168. 1.1, for example – 192.168. 1 is the network ID, and the final number is the host ID.
What is my local IP address?
