Advanced Lookup Tool

Welcome to Odextra’s Advanced Lookup Tool

Here you can perform WHOIS lookups, retrieve DNS records, view HTTP headers and check website status—all in one place. WHOIS data tells you who owns a domain and when it was registered or will expire. DNS records show how the Internet routes email, websites, and other services for that domain. HTTP headers reveal server, caching and security configurations for any URL. And our Website Status checker will tell you at a glance whether a site is up or down.

Simply enter a domain name or IP address above, choose the lookup type, and click “Lookup.” This tool is perfect for sysadmins, developers, security professionals—or anyone curious about the nuts and bolts of how the web works.
