NetOps Downloads & RevenueNetOps: Network Toolkit · App Store

Twelve network tools in one app for sysadmins and developers. NetOps finds the devices on your Wi-Fi, maps a managed switch over SNMP, checks TLS certificates and DNS, and probes hosts and ports, on iPhone and iPad.

LOCAL NETWORK
• LAN Scan — Sweeps your Wi-Fi subnet (up to 1,024 addresses), then reads the iOS ARP table to list each device's IP and MAC address, with the maker looked up from the MAC's OUI. Devices using a private (randomized) Wi-Fi address are marked as such. Export as CSV or JSON, or save a device to Hosts.
• Net Map — Point it at a managed switch or router that speaks SNMP v2c (GetBulk walks, read community). It reads system name, uptime and location; interfaces with status, speed and MAC; the ARP table with vendors; LLDP and CDP neighbors; MAC-to-switchport; and routed subnets. It reaches devices beyond your own subnet.

PROBES (TCP)
iOS gives apps no ICMP, so these tools time TCP connections, and say so on screen.
• Ping — TCP ping: each probe races connects to ports 80, 443, 53 and 22; an accept or a refusal counts as an answer. Count 1–100 or continuous, interval 0.2–2 s, with min/avg/max, jitter, loss and a latency chart.
• Traceroute — A TCP reachability check: up to 10 connect attempts to the destination, each waiting longer, until it answers. It does not list the routers in between.
• MTR — A continuous TCP ping to one destination with live loss, best, average, worst and jitter. No per-hop table.
• Port Scan — TCP connect scan of a host name or IPv4/IPv6 address: a 22-port common preset, a top-100 list, ports 1–1000, or any custom range. Each port is open, closed (refused), filtered (no answer) or unreachable (no route), and IPv4 is tried first.

CERTIFICATES
• SSL Check — Any host and port: the full chain labelled leaf, intermediate and root, iOS's own trust verdict, whether the certificate covers the host name, the failure reason, days to expiry, issuer, SANs and serial. Expired, self-signed and wrong-host certificates are still shown.

DNS AND IP
• Dig — Query A, AAAA, MX, TXT, CNAME, NS, SOA and PTR records from any resolver over UDP with EDNS0. The response code (NOERROR, NXDOMAIN, SERVFAIL, REFUSED) and a truncated answer are shown. SOA is printed in full and IPv6 in RFC 5952 short form.
• DNS Propagation — One name and record type across eight public resolvers at once (Google, Cloudflare, Quad9, OpenDNS, DNS.WATCH, Yandex), flagging disagreement.
• WHOIS — Domain and IP registration data over RDAP: dates, status, name servers, network.
• Reverse Lookup — IPv4 address to host name via PTR.
• CIDR Calculator — IPv4 subnet math: network, mask, wildcard, broadcast, first and last host, host counts, and whether an IP falls inside the block.

HOSTS AND HISTORY
• Hosts — Names, tags, notes and favorites. A host found by LAN Scan is matched by MAC, so it survives an IP change. Import from a CSV file, export to CSV, or sync from an HTTPS inventory API: any JSON list with dot-path field mapping (NetBox works), or an Ansibl
