# Network and IoT tools

Free tools we use ourselves when diagnosing connections, sizing IoT tariffs and planning networks.

### [Ping test](https://netavo.com/tools/ping-test)

Measure latency, jitter and packet loss on your connection, with loss split into upload and download and an estimate of call quality.

### [MTU and CGNAT test](https://netavo.com/tools/mtu-test)

Check whether full-size packets reach you over IPv4 and IPv6, find path MTU black holes, and see whether you are behind carrier-grade NAT.

### [IoT data usage calculator](https://netavo.com/tools/iot-data-usage-calculator)

Estimate monthly mobile data per device and across a fleet, counting protocol headers, TLS handshakes, keepalives, reconnects and firmware updates.

### [SIP channel calculator](https://netavo.com/tools/sip-channel-calculator)

How many SIP channels do you need? Erlang B sizing from the calls in your busiest hour, with the bandwidth by codec.

### [ICCID and IMSI decoder](https://netavo.com/tools/iccid-decoder)

Find a SIM's issuer, country and network from its ICCID or IMSI, using the ITU, Ofcom and Wikipedia lists.

### [Subnet calculator](https://netavo.com/tools/subnet-cheat-sheet)

Calculate any IPv4 or IPv6 subnet, with a cheat sheet of every IPv4 mask and host count and the common IPv6 prefix sizes.
