DevKay Network Toolkit is a comprehensive, terminal-based network utility suite designed for ethical hackers, network administrators, cybersecurity learners, and power users. This Python-powered toolkit consolidates a wide array of network operations — from local LAN scanning to external IP tracking, WHOIS lookups, DNS and SSL inspections, port scans, traceroutes, and live network monitoring — into a single intuitive interface.
-
Local Network Scanner
- Scans your LAN for active devices via ARP.
- Retrieves IP, MAC address, vendor (via MAC Vendors API), hostname, and online status.
-
External IP & Domain Tracker
- Resolves domains to IPs or accepts direct IP input.
- Fetches geolocation, ISP, organization, ASN, timezone, and more from ip-api.com.
-
WHOIS Lookup
- Gathers domain/IP registration details (owner, registrar, creation/expiry dates).
-
DNS Records Fetcher
- Retrieves common record types: A, AAAA, MX, NS, and TXT.
-
SSL Certificate Inspector
- Connects on port 443 and extracts issuer, validity period, and certificate details.
-
Port Scanner
- Scans a set of common TCP ports (e.g., 21, 22, 80, 443, 3306, 8080).
-
Nmap Integration
- Executes
nmap -A -T4scan ifnmapis installed.
Note: Nmap must be installed on your system and available in PATH for this feature to work.
- Executes
-
Traceroute
- Runs system
tracert(Windows) or falls back appropriately to visualize hop-by-hop path.
- Runs system
-
Live Network Monitor
- Periodically re-scans the LAN and alerts on device join/leave events.
-
Subnet Scanner
- Pings all hosts in a given IPv4 subnet (e.g.,
192.168.1.0/24).
- Pings all hosts in a given IPv4 subnet (e.g.,
-
HTTP Header Fetcher
- Performs an HTTP HEAD request to display response headers.
-
MAC Vendor Lookup
- Resolves a MAC address to its manufacturer via macvendors.com API.
- Language: Python 3.7+
- Modules:
