CIDR, binary, MAC, HTTP, and network reference tools

Showing all 13 tools in Networking.
CIDR Calculator
Calculate CIDR ranges, subnet masks, and IP blocks. Free CIDR calculator for network planning and IP address management.
NetworkingOffline
Subnet Calculator
Calculate subnets from CIDR notation. Free subnet calculator with host range, broadcast, and mask conversion.
NetworkingOffline
Binary Converter
Convert between binary, decimal, hexadecimal, and octal number systems. Free binary converter with step-by-step explanation.
NetworkingOffline
Hex Converter
Convert between hex, decimal, binary, and octal with group separators and a byte breakdown — for inspecting memory dumps and binary protocols.
NetworkingOffline
Decimal Converter
Convert decimal values to binary, hex, and octal with step-by-step division and subtraction methods for homework and interview prep.
NetworkingOffline
MAC Address Generator
Generate realistic random MAC addresses — including locally administered and unicast variants — for test fleets, lab VMs, and fixture data.
NetworkingOffline
Random IP Generator
Generate random IPv4 and IPv6 addresses, optionally from private or reserved-lean pools, for config samples, fixtures, and lab setups.
NetworkingOffline
IP Class Identifier
Classify any IP — public, private, loopback, link-local, multicast, or reserved — for both IPv4 classes and IPv6 special ranges.
NetworkingOffline
Port Number Reference
Searchable reference of common TCP/UDP ports and their services — 20/21/22/25/53/80/443/3306/5432 — with the default transport protocol.
NetworkingOffline
HTTP Status Codes
Every HTTP status code from 100 to 511, grouped by class, with the reason phrase and a one-line note on when you will actually see it.
NetworkingOffline
MIME Types
Look up the MIME type for any file extension and reverse-lookup which extensions map back — across text, image, audio, video, and application types.
NetworkingOffline
User-Agent Parser
Break any User-Agent string into browser, version, engine, OS, and device type —including bots and crawler signatures — without a server round-trip.
NetworkingOffline
URL Parser
Split any URL into protocol, hostname, port, path, decoded query parameters, and fragment, with each component listed and copyable.

Networking — Free Online Browser Tools

Networking tools cover subnet and CIDR calculations, binary, hex, and decimal conversions, MAC and IP address generation, and quick references for ports, HTTP status codes, MIME types, and user-agent parsing. Built for developers, students, and IT professionals, every calculation happens locally and instantly — no servers involved. Plan an IP allocation with CIDR and subnet calculators, convert between number bases for a computer science assignment, or generate test MAC and IP addresses for your lab. When something breaks, the port reference, HTTP status tables, and MIME lookups help you identify the problem quickly — and the user-agent and URL parsers are perfect for inspecting request strings.
