Network Tools for Infrastructure Engineers

Current network connection details

View detailed information about your current network connection including IP address, subnet mask, gateway, DNS servers, and interface type. Essential for quick network troubleshooting on the go.

Check your global IP address

Instantly check your public IP address as seen by external servers. Useful for verifying VPN connections, NAT configurations, and firewall rules.

Measure download & upload speed

Measure your network download and upload speeds with accurate bandwidth testing. Monitor network performance and verify ISP service levels from your iOS device.

Subnet calculation & CIDR conversion

Calculate subnet masks, network addresses, broadcast addresses, and host ranges from CIDR notation or subnet masks. Supports IPv4 subnetting with visual binary representation. The essential tool for network planning and IP address management.

Network / broadcast address calculation

Calculate network address, broadcast address, and usable host range for any IP and subnet mask combination. Essential for network segmentation and addressing.

VLAN subnet design calculation

Design VLAN subnets with automatic IP range allocation. Plan multiple VLANs within a supernet and calculate optimal subnet sizes for each segment.

IP geographic information

Look up geographic location, ISP, organization, and ASN information for any IP address. Useful for investigating suspicious traffic, verifying CDN routing, and geolocation-based access control.

Bandwidth & transfer time calculation

Calculate file transfer times, required bandwidth, and data throughput for various network speeds. Essential for capacity planning and SLA estimation.

MTU/MSS value calculation

Calculate Maximum Transmission Unit and Maximum Segment Size values for various encapsulation types including GRE, IPsec, VXLAN, and PPPoE.

Network latency simulation

Simulate network latency to understand the impact of round-trip time on application performance. Visualize how different latency values affect user experience.

Check port open status

Test TCP port connectivity to any host. Check if specific ports are open, closed, or filtered. Essential for firewall rule verification and service availability monitoring.

AS number lookup

Look up Autonomous System numbers, prefixes, and peering information. Essential for BGP troubleshooting and network path analysis.

Discover devices on local network

Discover Bonjour/mDNS services and devices on your local network. Find printers, servers, IoT devices, and other network-attached resources.

Send magic packets to wake devices

Send Wake-on-LAN magic packets to remotely power on computers and network devices. Save device MAC addresses for quick access.

Identify vendor from MAC address

Identify the manufacturer of a network device from its MAC address OUI prefix. Includes a comprehensive database of IEEE-registered vendors.

WiFi channel design & interference avoidance

Plan optimal WiFi channel assignments for 2.4GHz and 5GHz bands. Visualize channel overlap and minimize interference in multi-AP deployments.

Send SNMP traps

Send SNMPv2c trap notifications for testing monitoring systems and NMS configurations. Customize OIDs, community strings, and varbinds.

Send syslog messages via UDP/TCP/TLS

Send syslog messages over UDP, TCP, or TLS for testing log aggregation systems like Splunk, Elasticsearch, and Graylog.
