Networking Calculators
Professional-grade tools for network planning, troubleshooting, and optimization. All calculations run locally in your browser — no data leaves your device.
Subnet Calculator
Divide networks into subnets, calculate IP ranges, broadcast addresses, and available hosts per subnet.
PoE Budget Calculator
Match devices like cameras and access points to Power-over-Ethernet switch capacity.
Bandwidth Planner
Determine ISP speed requirements based on user count and activity types.
WiFi Coverage Estimator
Calculate approximate AP placement and count based on floor area, wall materials, and client density.
Cable Loss Calculator
Calculate decibel drop over copper or fiber runs to check signal integrity.
File Transfer Timer
Calculate real-world data migration time, including protocol overhead.
Latency Calculator
Estimate network latency based on physical distance and transmission medium. Calculate RTT for fiber, copper, and satellite.
MTU Calculator
Calculate effective MTU through tunnels and VPNs. Account for GRE, IPsec, VXLAN, WireGuard encapsulation overhead.
Throughput Calculator
Calculate real network throughput accounting for protocol overhead. Understand efficiency from Ethernet, IP, and TCP/UDP headers.
VLAN Planner
Estimate broadcast domain sizes and recommend VLAN segmentation based on device counts.
IP/CIDR Converter
Convert between IP addresses, CIDR notation, subnet masks, and binary representations.
CIDR Aggregator
Combine multiple subnets into minimal CIDR blocks. Optimize routing tables and firewall rules.
Uptime Calculator
Calculate SLA percentages, allowed downtime, and understand five-nines availability.
RAID Calculator
Calculate storage capacity, efficiency, and fault tolerance for different RAID configurations.
Port Density Calculator
Calculate switch port requirements based on device counts, uplinks, and growth projections.
WiFi Channel Planner
Plan optimal WiFi channel assignments to minimize interference across 2.4GHz and 5GHz bands.
DNS TTL Calculator
Plan DNS record TTL values and understand propagation times. Calculate optimal TTL for migrations.
MAC Address Tool
Parse, validate, and format MAC addresses. Look up vendor information from the OUI.
Link Aggregation Calculator
Calculate aggregate bandwidth, redundancy benefits, and load balancing for bonded links.
Network Growth Planner
Project network infrastructure needs based on user growth. Plan for ports, bandwidth, and IP addresses.
