HE.NET Network Tools vs SimpleNet Tools

This suite of networks tools implements most of the network diagnostics that you need as a Network Engineer or System Administrator. Please help us improve it by giving us feedback. + ARP / NDP: Lookup local devices found on your network using either ARP (IPv4) or NDP (IPv6). + Bonjour Browser: See what DNS-SD/Bonjour services are available on your network + DNS lookup: Search for a servers DNS zone records such as SOA, NS, A, AAAA, MX, PTR. + Interface Information: Get information regarding your device's current network state. + IP Calculator: Calculate the Netmask, Wildcard, Network, Host range, and Broadcast for a given subnet. + iperf: Check bandwidth against remote iperf services. + One Time Password: Securely store and view your TOTP and HOTP (two-factor authentication) codes. TOTP codes are available on the Apple Watch. + Ping: Send ICMP packets to a single IPv4/IPv6 address. + Ping Sweep: Send ICMP packets to an entire subnet range. + Traceroute: Find the route packets take to reach your destination. + Progressive Traceroute: Get detailed statistics for a given route. + Port Scan: Scan a list of TCP ports on any server. + Routing Table: See your local device's routing table. + SSL/TLS Information: Check available ciphers, protocols and what's being used when connecting to a remove service. + Whois: Get information regarding network resources. + NO ADS! Note: Recent iOS releases secure certain low-level network information, and as such will not be available in-app, such as MAC addresses for other network devices.

SimpleNet Tools is a focused network toolkit for IT folks who need basic checks from a phone — without ads getting in the way. Run common diagnostics on the go: ping a host, look up DNS records, check a TCP port, follow a traceroute, probe TLS and certificates, look up whois/RDAP registration, and estimate IP city/ISP/ASN. Native ICMP and TCP run on iOS production builds so results reflect real network behavior from your device. TOOLS • Ping — ICMP echo with latency, loss, and jitter • DNS — A, AAAA, CNAME, MX, TXT, and NS via the resolver you choose (device DNS where available, or Cloudflare) • Port — TCP connect check: open, closed, or filtered • Trace — ICMP traceroute with hop-by-hop TTL probes • TLS — HTTPS reachability, security headers, and certificate transparency lookup • Location — IP city, ISP, and ASN (including this device’s public IP) • Whois — RDAP registration for a domain or IP: owner, registrar, dates, nameservers EXTRA • Saved addresses — keep frequent hosts on-device for quick re-use • About — version, release notes, Terms, and Privacy No account. No ads. No in-app purchases. You choose the host or address to test; checks run from your device. Made by anollopa for people who just need simple network commands on mobile.
