1. Bluetooth Low Energy Scanner: Scans for nearby Bluetooth Low Energy (BLE), Bluetooth LE, or Bluetooth Smart devices.
2. IPv4 Subnet Scanner: Scans for pingable IP addresses from [].[].[].1 to [].[].[].254 within a specified subnet.
3. mDNS Scanner: Scans for Multicast DNS (mDNS) broadcasts and collects associated service information.
4. UPnP Scanner: Scans for Universal Plug and Play (UPnP) broadcasts, including Digital Living Network Alliance (DLNA), and collects associated device information.
5. Route Tracer: Traces the route to a target server, showing each hop along the route with its corresponding IP address.
6. TCP Port Scanner: Scans Transmission Control Protocol (TCP) ports from 0 to 65535 on a target server and reports the open ports.
7. Pinger: Pings a target server and reports the IP address, Time To Live (TTL), and time.
8. File Hash Calculator: Calculates Message Digest 5 (MD5), Secure Hash Algorithm 1 (SHA1), Secure Hash Algorithm 224 (SHA224), Secure Hash Algorithm 256 (SHA256), Secure Hash Algorithm 384 (SHA384), and Secure Hash Algorithm 512 (SHA512) hashes of files.
9. String Hash Calculator: Calculates Message Digest 5 (MD5), Secure Hash Algorithm 1 (SHA1), Secure Hash Algorithm 224 (SHA224), Secure Hash Algorithm 256 (SHA256), Secure Hash Algorithm 384 (SHA384), and Secure Hash Algorithm 512 (SHA512) hashes of a string.
10. CVSS Calculator: Uses Common Vulnerability Scoring System (CVSS) v3.1 to calculate base score of exploitability.
11. Base Encoder: Encodes a string into binary (Base2), ternary (Base3), quaternary (Base4), quinary (Base5), senary (Base6), octal (Base8), decimal (Base10), duodecimal (Base12), hexadecimal (Base16), Base32, Base32Hex, Base36, Base58, Base62, and Base64.
12. Morse Code Translator: Translates English to Morse code and vice versa.
13. QR Code Generator: Generates QR (Quick Response) Code from a string.
14. OGP Data Extractor: Extracts Open Graph Protocol (OGP) data of a webpage.
15. Series URI Crawler: Crawls webpages generated from a combination of Uniform Resource Identifier (URI) and number series, and lists the available ones.
16. DNS Record Retriever: Retrieves Address (A), IPv6 Address (AAAA), Any Record (ANY), Certification Authority Authorization (CAA), Child Delegation Signer (CDS), Certificate (CERT), Canonical Name (CNAME), Delegation Name (DNAME), Domain Name System Key (DNSKEY), Delegation Signer (DS), Host Information (HINFO), IPsec Key (IPSECKEY), Next Secure (NSEC), Next Secure version 3 Parameters (NSEC3PARAM), Naming Authority Pointer (NAPTR), Pointer (PTR), Responsible Person (RP), Resource Record Signature (RRSIG), Start of Authority (SOA), Sender Policy Framework (SPF), Service Locator (SRV), SSH Fingerprint (SSHFP), Transport Layer Security Authentication (TLSA), Well Known Services (WKS), Text (TXT), Name Server (NS), and Mail Exchange (MX) records of a domain name (forward lookup) or an IP address (reverse lookup).
17. WHOIS Retriever: Retrieves WHOIS information about a domain name.
18. Wi-Fi Details Viewer: Displays details of the currently connected Wireless Fidelity (Wi-Fi) network.
