IP Subnet Calculator
This tool is designed to help network engineers and IT professionals quickly calculate and visualize IPv4 subnet information. By entering an IP address and subnet mask, it generates essential details such as network address, broadcast address, valid host range, and number of usable hosts—making subnet planning and troubleshooting more efficient and error-free., enter any valid IPv4 subnet and get the following info quickly:
  • Subnet ID
  • Subnet Mask
  • Broadcast IP
  • Usable IP Range
  • Subnet ID Binary and Decimal Values
  • Subnet Mask Binary and Decimal Values
IP Subnetting
This tool simplifies IPv4 subnetting by allowing users to input a major (super) subnet and either a desired mask length or the number of hosts per subnet. Based on this input, the tool automatically generates a complete subnetting table, detailing network addresses, broadcast addresses, and usable host ranges for each resulting subnet—making it ideal for efficient network planning and address allocation
  • Super Subnet as example: 10.0.0.0/8
  • Number of desired hosts in the output subnet like 150 hosts per subnet mask length range from 1 - 32
IP Summarization
This tool simplifies IPv4 address management by accepting a list of individual IPv4 subnets as input and automatically computing the most efficient supernet (summary route) that encompasses them. It’s designed to help network engineers consolidate routing entries, improve clarity in route tables, and support scalable network design by finding the minimal set of aggregate subnets without sacrificing coverage or precision
