Tools and guides

Explore network tools and learn what their results mean. The IP Location lookup is available now; the other entries are informational guides, not interactive checkers.

• IP Location

  Look up a public IP address to see its estimated location, provider, timezone, and coordinates on a map. Location is approximate and does not identify a person's exact address.

• Speed Test

  A speed test measures a connection's download speed, upload speed, and response time to a test server. Results can vary with Wi-Fi conditions, network traffic, and the server used.

• DNS Lookup

  A DNS lookup checks records that connect a domain name with internet services, such as IP addresses for a website or mail servers. The records returned depend on the DNS provider and record type.

• WHOIS Lookup

  A WHOIS lookup can show public registration and administrative details for a domain name or IP network. Some information may be redacted, privacy-protected, or unavailable.

• Port Checker

  A port checker tests whether a network service can be reached through a particular port. Only check systems and services you own or are authorized to administer; firewalls and network rules affect results.

• SSL Checker

  An SSL checker reviews a website's TLS certificate, including whether it is trusted and when it expires. A valid certificate helps authenticate a website and protect data in transit.

• Mac Address Lookup

  A MAC address lookup may identify the manufacturer associated with a network adapter's hardware address. A MAC address is used on local network links and generally cannot be looked up remotely from a public IP address.

• Ping

  Ping sends network echo requests to measure round-trip response time and check whether a host responds. Some networks block these requests, so no reply does not always mean a service is offline.

• Traceroute

  Traceroute shows the network hops that may be taken toward a destination and the response times reported along the way. Routers can filter or deprioritize these probes, so the displayed path may be incomplete.

• Port Number

  A port number identifies a particular service or application endpoint on a network connection. TCP and UDP use separate port spaces; for example, HTTPS commonly uses TCP port 443.
