Network and IoT tools
Free tools we use ourselves when diagnosing connections, sizing IoT tariffs and planning networks.
All 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.
Test your ping →MTU and CGNAT 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.
Test your connection →IoT data usage calculator
Estimate monthly mobile data per device and across a fleet, counting protocol headers, TLS handshakes, keepalives, reconnects and firmware updates.
Estimate data usage →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.
Size a SIP trunk →ICCID and IMSI decoder
Find a SIM's issuer, country and network from its ICCID or IMSI, using the ITU, Ofcom and Wikipedia lists.
Decode a SIM →Subnet calculator
Calculate any IPv4 or IPv6 subnet, with a cheat sheet of every IPv4 mask and host count and the common IPv6 prefix sizes.
Calculate a subnet →Need a hand with the numbers?
