NetProbe vs deepdig.dev

When a connection acts up, reach for NetProbe. Find responding hosts, check latency and TCP ports, trace routes, inspect DNS and HTTPS, and save the evidence—all from your iPhone or iPad. CHECK THE CONNECTION Use real IPv4 ICMP Ping with live latency charts and packet-loss statistics. Trace responding hops to a destination. Compare up to three targets in a timed foreground Stability session, with a timeline and notes to capture what happened. EXPLORE YOUR LOCAL NETWORK Scan your LAN for responding IPv4 hosts, label saved results, and jump into Ping or a port check. Browse supported Bonjour services, inspect their advertised addresses and ports, and test a selected TCP endpoint. SEE WHICH PORTS RESPOND Check common TCP ports or choose your own. Use web, database and other port presets to check whether an endpoint accepts a connection. LOOK CLOSER AT DNS AND HTTPS Look up A, AAAA, MX, TXT, CNAME, NS, SOA and PTR records through Google or Cloudflare. Compare both providers side by side. Inspect HTTPS status, redirects and available connection timings. Follow DNS results into selected-address TLS checks that preserve the hostname and system trust. KEEP A USEFUL RECORD Save diagnostics in local History and revisit the details. Compare supported service/TCP or DNS runs before and after a change. Preview reports with detail redaction, then share text or CSV when you need to explain what you found. THE EVERYDAY EXTRAS Send Wake-on-LAN magic packets to compatible devices using saved shortcuts. Calculate IPv4 subnet ranges, masks and broadcast addresses offline. Look up available Whois registration details for supported domains. BUILT FOR IPHONE AND IPAD A focused phone layout and an iPad sidebar workspace. Dark, light and automatic appearance. No app account required. No ads or subscriptions. TRY THE TOOLKIT. UNLOCK IT ONCE. Start a seven-day free trial. Keep access with a one-time lifetime in-app purchase; the app shows your regional price before purchase. Diagnostics contact the targets and providers you choose. Saved history stays on your device until you export it. Discovery shows responding hosts and supported advertised services, not a guaranteed inventory. Missing replies do not prove a host is offline. Stability runs in the foreground; before-and-after comparison supports service/TCP and DNS runs. Wake-on-LAN requires compatible hardware and network settings; sending a packet does not confirm a wake. Review reports before sharing.

deepdig is a free toolbox of network diagnostics built for sysadmins, DevOps engineers and hosting operators — the checks you run every day, faster and more detailed, with no account and no ads. Enter a domain, IP or paste raw data. Checks run in parallel on our servers and results stream in live, each finding graded by severity with a plain-English explanation of why it matters. TOOLS • DNS diagnostics — records, delegation and glue consistency, full DNSSEC chain validation from the root, propagation across 18 public resolvers, and a hop-by-hop recursion trace • SSL/TLS — certificate chain, expiry, hostname match, trust, protocol versions, HSTS • WHOIS — registrar, dates, EPP status codes for domains; RIR allocation, ASN and abuse contacts for IPs • Mail tester — SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI, MX reachability and STARTTLS • Email header analyzer — paste a raw email, get the Received chain as a timed hop-by-hop trace with SPF/DKIM/DMARC verdicts • DNSBL / blacklists — check IPs and domains against major blocklists, Spamhaus included • HTTP headers — security headers, redirect chain, cookie flags, server fingerprint • HTTP/3 — ALPN negotiation, Alt-Svc advertisement and CDN detection • IP info — ASN, announced prefix, rDNS, country and hosting classification • Certificate Transparency log search • Subnet/CIDR calculator and a password generator WATCHES — GET NOTIFIED WHEN THINGS CHANGE Put a domain or IP on watch and deepdig re-checks it for you. You get a push notification only when something actually changes: a certificate crossing 14, 7 or 1 day to expiry (and a recovery notice when it renews), a new blacklist listing or a delisting, or a changed DNS record set. No noise, no daily digests — alerts only on real transitions. BUILT THE WAY YOU'D WANT IT • Results stream in as each check completes — no spinners • Every run is saved as a shareable permalink snapshot • History and side-by-side comparison for any target • Share a URL or domain from any app to open the right tool prefilled • Dark mode that follows your system • No account, no ads, no tracking, no analytics. Free. deepdig is the mobile companion to deepdig.dev — same engine, same results, in your pocket.
