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.
