Quick lookups for IP addresses, DNS records and domain registration details.
About Network Tools
SimplyToolbox's network tools give you fast answers to everyday networking and domain questions without the command line. The IP Lookup tool shows the approximate geolocation, network and provider behind any IP address — useful for checking where a connection originates or troubleshooting access. The DNS Lookup tool retrieves a domain's records, including A, AAAA, MX, TXT and CNAME entries, so you can verify how a site or email is configured. The WHOIS Lookup tool returns public domain registration details such as the registrar and key dates. These tools query public services for the minimum information needed — only a domain or IP, never your private files — and present the results in a clear, readable format.
