NetTracer – Traceroute
IPv4 & IPv6 network path
Free · Designed for iPad. Not verified for macOS.
New: check IPv4, IPv6, DNS and NAT64 before you trace, see exactly which address will be probed, and follow every hop on a clear route map.
See the path your traffic takes across the internet, hop by hop.
NetTracer runs a real traceroute from your iPhone or iPad over ICMP or UDP, in IPv4 or IPv6. Each router along the way appears on a route map with its address, name, country, network (ASN) and operator, and a colour that tells you at a glance where latency builds up.
CHECK YOUR NETWORK FIRST
• Real IPv4 and IPv6 connectivity tests, not just what the system reports
• DNS resolver check and NAT64 / 464XLAT detection, useful on IPv6-only mobile networks
• Wi-Fi or cellular, with LTE / 5G and Low Data Mode shown
• While you type, see the A and AAAA records of the host and which IP version the trace will use, with a warning if it cannot work
FOLLOW EVERY HOP
• Fast first pass, then continuous measurement: minimum, average and maximum latency, packet loss and a latency chart for each hop
• Pause and resume measurement at any time
• Clear status when the destination is not reached: silent hops, filtering router or hop limit, with a hint on what to try next
• Reverse DNS, country, ASN and ISP for public addresses; private and carrier-grade NAT addresses are recognised
MADE FOR DAILY USE
• Favorites and history
• Share the result as text
• Adjustable hop limit, reply timeout and early stop on silent hops
• Light and dark themes, Dynamic Type, 17 languages
PRIVACY
No account, no tracking, no ads. Probes go straight from your device to the hosts you trace. To show location and network details, the public addresses of the hops are looked up with ip-api.com.
• New network card: real IPv4, IPv6 and DNS tests, NAT64 detection, Wi-Fi / cellular with LTE / 5G
• DNS preview while you type, with the IP version the trace will use and warnings if it cannot work
• Redesigned trace screen: route map coloured by latency, clear status and hints, latency chart for each hop
• Much better support for IPv6-only and tunnelled mobile networks
• Stop on silent hops, pause and resume measurement, favorites on the home screen
• Many fixes: stopping a trace, unknown host names, IPv6 address entry, long sessions
