NetLab Toolkit

NetLab Toolkit is a professional-grade network utility app built for IT administrators, network engineers, and anyone who needs reliable network diagnostics in the field. No ads. No subscriptions. No cloud. Just tools that work. PING Send real ICMP echo requests to any host or IP address. Automatic DNS resolution shows you exactly which IP you're hitting before the first packet is sent. Reverse DNS lookup displays the PTR record so you always know what you're pinging. Live results stream to screen with min, avg, max, and packet loss statistics. TRACEROUTE Trace the full hop-by-hop path from your device to any destination. See every router your traffic passes through, response times at each hop, and where timeouts occur. Essential for diagnosing routing issues and network latency problems. PORT SCANNER Scan 20 of the most common TCP ports on any host in seconds. Instantly see which services are running and accessible. Covers everything from FTP and SSH to MySQL, RDP, Redis, and MongoDB. A fast first step in any network audit. DNS LOOKUP Full DNS record resolution supporting A, AAAA, MX, TXT, NS, CNAME, and SOA record types. Toggle between your device's local DNS resolver and Google's public DNS to compare results, essential for diagnosing split-horizon DNS, VPN environments, and AdGuard or Pi-hole setups. Type an IP address for automatic reverse PTR lookup. WI-FI INFO View your current connection details including SSID, signal strength, link speed, frequency, local IP, and MAC address. Fetch your public IP address with full geolocation including ISP, ASN, city, region, and timezone. Scan nearby Wi-Fi networks to see signal strength, frequency band, and security type for every network in range. SUBNET CALCULATOR Full CIDR subnet calculations including network address, broadcast address, subnet mask, wildcard mask, first and last usable host, total addresses, and usable host count. Binary mask display and a 32-bit visual network/host bit breakdown make it easy to understand and explain any subnet. WHY NETLAB TOOLKIT?
