Subdomains often reveal which internal systems, websites, or platforms a company operates. Finding subdomains is an important part of security assessments, penetration tests, or general research, as it can uncover potential attack surfaces that might otherwise remain hidden.

The SubDomainFinder from binsec.tools identifies subdomains of a domain by combining several methods:

• It accesses the CertWatch database from binsec.tools – a collection of public SSL/TLS certificates where subdomains often appear.
• Additionally, it performs DNS queries using a predefined subdomain wordlist to systematically test commonly used subdomains.
• Moreover, targeted search queries are sent to google.com to discover additional subdomains that appear in public search results and might otherwise be overlooked.

A tool that displays your own public IPv4 and IPv6 addresses is now online at binsec.tools. It’s not the first tool that does that, but it’s free of advertising and tracking:

What is my IP address?

From a linux shell you can also call

$ curl https://ip.binsec.tools/

and get your IP back in JSON format

{"ip": "93.207.237.237", "version": 4}

or get the IPv4 or IPv6 address

$ curl https://ip4.binsec.tools/
$ curl https://ip6.binsec.tools/

In the browser you may stil use:

You are looking for a free online tool, that checks and test the ssl/tls configuration on a specific custom port, alternative to 443? Then checkout the binsec.tool SSLCheck – there you can specify the port that should be tested, like 8443. The SSLScan fo binsec.tool will give you an overview over the protocols and ciphers of the TLS configuration and checks the level of security. It even supports testing StartTLS for SMTP, IMAP and LDAP.
