Net Tools – Network Toolkit

NikBit

About this app

Net Tools is a complete network toolkit for engineers, sysadmins, students and anyone who works with networks. Calculators, diagnostics, scanners and lookups — all in one fast, clean app with full dark mode support.

▸ HOME DASHBOARD
See your connection at a glance: WiFi SSID/BSSID, signal strength and band (2.4 / 5 / 6 GHz), local IP, subnet mask, gateway and DNS servers, plus your public IP with geolocation and ISP.

▸ CALCULATORS
• IPv4 Calculator — mask, network, broadcast, host range, binary view
• IPv6 Calculator — expanded form, prefix, address type
• VLSM Calculator — split a network into custom subnets
• Converter — binary / hex / decimal / IP

▸ DIAGNOSTICS
• Ping — host availability and latency
• Traceroute — hop-by-hop path to any host
• Latency Monitor — live ping graph over time
• Speed Test — measure download and upload throughput

▸ SCANNING
• IP Scanner — discover live hosts on your network
• Port Scanner — TCP, UDP or both, with common / 1–1024 / custom ranges and service detection (DNS, SNMP, NTP, NetBIOS, SSDP and more)
• WiFi Scanner — nearby networks, channels and signal
• IP Blacklist Check — check an IP against DNS blacklists

▸ LOOKUP
• DNS Lookup — query ANY DNS server (default 8.8.8.8), multiple record types at once (A, AAAA, MX, NS, TXT, CNAME, PTR, SOA, SRV)
• WHOIS — domain and IP registration data
• IP Info — geolocation, ASN and ownership
• BGP / ASN Lookup — prefixes and routing information
• MAC OUI Lookup — identify the hardware vendor from a MAC address
• SSL Inspector — certificate chain, expiry and details
• HTTP Headers — inspect the response headers of any URL
• HTTP Request — send custom GET / POST requests

▸ TOOLS
• Wake on LAN — power on devices with a magic packet
• NTP Test — query any NTP server and compare its time with your device clock (offset, round-trip, stratum)

WHY NET TOOLS
• Clean, modern Material design
• Full dark theme with high-contrast text
• Fast and lightweight
• Long-press any result to copy it to the clipboard

NOTE: The scanning features are intended for networks you own or are authorized to test. Always respect local laws and your network policy.

What’s new

• NEW: NTP Test — query any NTP server and check your device clock offset
• Port Scanner now supports TCP, UDP or both, with service probes (DNS, SNMP, NTP, NetBIOS, SSDP)
• DNS Lookup: choose any DNS server and query multiple record types at once
• Improved dark mode — higher text contrast and readability
• Various fixes and polish
