Networking Infrastructure Tools
Calculators for IP subnets, CIDR notation, transfer times, bandwidth capacities, and Wi-Fi coverage.
Free online general tools.
Binary to IP Address
Convert a 32-bit binary value back into a dotted-decimal IPv4 address.
CIDR Calculator
Convert between slash notation (/8 to /32), dotted decimal subnet masks, and total available host capacities.
Data Transfer Calculator
Convert data transfer volume units across bytes, Kilobytes, Megabytes, Gigabytes, and Terabytes (Binary vs Decimal).
Download Time Calculator
Estimate exact download time for large files (ISOs, game patches, backups) across various connection speeds.
IP Address to Binary
Convert a dotted-decimal IPv4 address into its 32-bit binary representation.
IP Decimal Converter
Convert an IPv4 address to and from its 32-bit decimal integer equivalent.
IP Hex Converter
Convert an IPv4 address to and from its hexadecimal representation.
IP Subnet Calculator
Calculate network address, broadcast address, usable host IP range, and subnet mask in real-time.
IPv4 Range Calculator
Determine start IP, end IP, total addresses, and class categorization from start/end or subnet block.
IPv4 to IPv6 Converter
Convert an IPv4 address into its IPv4-mapped IPv6 form.
IPv6 Calculator
Compress, expand, and subnet 128-bit IPv6 hexadecimal addresses and evaluate prefix /64 block boundaries.
IPv6 to IPv4 Converter
Extract the embedded IPv4 address from an IPv4-mapped IPv6 address.
Network Bandwidth Calculator
Calculate required bandwidth capacity in Mbps/Gbps based on concurrent user streams and payload size.
Network Cost Calculator
Calculate enterprise dedicated internet access (DIA), dark fiber lease, cloud egress, and transit costs.
Subnet Count Calculator
Calculate how many subnets and usable hosts per subnet result from moving to a new prefix length.
Upload Time Calculator
Estimate upload completion duration for video rendering, cloud backups, and FTP transfers at varying upload speeds.
VLSM Calculator
Allocate variable-length subnets from a base network according to each department's host requirements.
Wi-Fi Coverage Estimator
Estimate access point (AP) requirements and RF signal propagation radius through drywall, concrete, and brick walls.
Wildcard Mask Calculator
Convert a CIDR prefix into its subnet mask and inverse wildcard mask (used in ACLs/OSPF).
