HE.NET Network Tools is a powerful suite of network diagnostics designed for Network Engineers and System Administrators. Developed by Hurricane Electric LLC, this app provides a wide range of tools to help you troubleshoot and analyze your network.

With HE.NET Network Tools, you can perform ARP and NDP lookups to identify devices on your network. The Bonjour Browser allows you to discover DNS-SD/Bonjour services available on your network. The DNS lookup feature lets you search for DNS zone records such as SOA, NS, A, AAAA, MX, and PTR.

The app also provides interface information, giving you insights into your device's current network state. The IP Calculator helps you calculate the netmask, wildcard, network, host range, and broadcast for a given subnet. You can also use the iperf tool to check the bandwidth against remote iperf services.

In addition, HE.NET Network Tools offers features like One Time Password, which securely stores and views your TOTP and HOTP codes for two-factor authentication. The Ping tool allows you to send ICMP packets to a single IPv4/IPv6 address, while the Ping Sweep feature sends ICMP packets to an entire subnet range. Traceroute helps you find the route packets take to reach your destination, and Progressive Traceroute provides detailed statistics for a given route.

Other useful tools include Port Scan, Routing Table, SSL/TLS Information, and Whois. The app also boasts a clean and user-friendly interface, ensuring a smooth user experience. Best of all, HE.NET Network Tools is completely free and ad-free.

Please note that certain low-level network information, such as MAC addresses for other network devices, may not be available due to recent iOS security updates. However, this does not detract from the overall functionality and usefulness of HE.NET Network Tools.
