Just type your keyword, and the tool tells you if it’s available or already taken. It's lightning-fast, intuitive, and perfect for brainstorming brand ideas.
2. Domain Generator – Seox Domain Generator

3. WHOIS Lookup – Seox WHOIS Tool
Understanding who owns a domain or when it expires can help with strategic decisions, like domain acquisitions or avoiding trademark issues. The WHOIS tool provides ownership data, registrar info, and important dates with just one search.
4. Reverse IP Lookup – Seox IP Lookup
This tool helps you identify all domains hosted on the same IP address. It’s essential for investigating shared hosting environments, spotting PBNs, or checking if a competitor runs multiple sites from one server.
5. DNS Lookup – Seox DNS Lookup
DNS configuration is critical to a website’s operation. The DNS Lookup tool allows you to view all the DNS records (A, MX, TXT, CNAME, etc.) for a given domain. It’s especially helpful during domain migrations, mail setups, and SSL verifications.
6. Blocklist Checker – Seox Blocklist Lookup
Is your domain or IP blacklisted? This tool scans popular blocklists to verify your domain's reputation. If your server or email IP appears on a spam or malware blacklist, you can identify it and take quick action.

Find out where a domain is physically hosted and who the service provider is. It’s valuable for analyzing server speeds, GDPR compliance, and choosing region-specific hosting for better performance.
8. Open Ports Scanner – Seox Open Ports Tool
Ensure your server is secure by scanning for open ports. Open ports may be vulnerable to attacks. This tool allows you to check if critical ports like 21 (FTP), 22 (SSH), 80 (HTTP), or 443 (HTTPS) are exposed unnecessarily.
