Domain & IP Tools
Professional tools for IT experts to look up domain information, identify network devices, and analyze IP addresses with precision and accuracy.
What Are Domain & IP Tools?
Domain and IP tools are essential utilities for network administrators, security professionals, and IT specialists who need to gather information about domains, IP addresses, and network devices. These tools provide critical insights for network management, security analysis, and troubleshooting.
Whether you're investigating domain ownership, planning network infrastructure, identifying unknown devices on your network, or tracking the geographic location of IP addresses, these tools provide the detailed information you need to make informed decisions.
Our suite of domain and IP tools includes WHOIS lookup, IP geolocation, MAC address lookup, and subnet calculation—all designed to give you accurate, comprehensive information about the digital assets you're investigating.
Domain & IP Tools
WHOIS Lookup
Retrieve comprehensive domain registration information including owner details, registration dates, and nameservers.
IP Geolocation
Find the geographic location of any IP address including country, city, ISP, and timezone information.
What's My IP
Instantly see your current IP address location on a map with detailed geographic and network information.
MAC Address Lookup
Identify hardware vendors from MAC addresses using the latest IEEE OUI database for network device identification.
Subnet Calculator
Calculate subnet masks, network addresses, broadcast addresses, and IP ranges for network planning.
MAC Address Lookup Tool
Our MAC Address Lookup tool helps network administrators identify the manufacturer of network devices using their MAC addresses. This is essential for:
- Identifying unknown devices on your network
- Verifying hardware inventory during audits
- Troubleshooting network connectivity issues
- Enhancing network security by detecting unauthorized devices
The tool uses the latest IEEE OUI (Organizationally Unique Identifier) database to provide accurate vendor information for any MAC address you enter.

Common Domain & IP Tool Use Cases
Domain Ownership Investigation
When you need to contact a domain owner or verify domain registration details, our WHOIS Lookup tool provides comprehensive information about domain ownership, registration dates, and contact information.
Use WHOIS Lookup Tool →Network Security Monitoring
Security professionals need to identify unknown devices on their networks and track suspicious IP addresses. Our MAC Address Lookup and IP Geolocation tools help you quickly gather intelligence about potential security threats.
Network Planning and Segmentation
When designing or expanding networks, proper subnet planning is essential. Our Subnet Calculator helps network engineers determine optimal subnet masks, calculate available IP addresses, and plan efficient network segmentation.
Use Subnet Calculator Tool →Geographic Traffic Analysis
Understanding where your website visitors or application users are located can help with content delivery optimization and compliance requirements. Our IP Geolocation tool provides detailed location information for any IP address.

What information can I get from a WHOIS lookup?
A WHOIS lookup provides domain registration details including the registrar, registration and expiration dates, nameservers, and sometimes contact information for the domain owner (though this may be private). It's useful for verifying domain ownership, checking domain age, and finding contact information for legitimate purposes.
How accurate is IP geolocation data?
IP geolocation accuracy varies by region and provider. Generally, country-level accuracy is very high (95-99%), while city-level accuracy ranges from 50-80% depending on the region. Rural areas typically have lower accuracy than urban centers. Our tool aggregates data from multiple sources to provide the most reliable information possible.
What is a MAC address and why would I need to look it up?
A MAC (Media Access Control) address is a unique identifier assigned to network interfaces. Each network device has a unique MAC address assigned by the manufacturer. Looking up a MAC address helps identify the device manufacturer, which is useful for network inventory, troubleshooting unknown devices, and security monitoring.
How do I calculate how many IP addresses are in a subnet?
The number of usable IP addresses in a subnet is calculated as 2^(32-prefix length) - 2 for IPv4. For example, a /24 subnet has 2^(32-24) - 2 = 254 usable addresses. The subnet calculator tool automatically performs these calculations for you, showing available IPs, network address, broadcast address, and more.
Can these tools help with GDPR compliance?
Yes, our IP geolocation tool can help with GDPR compliance by identifying when users are connecting from EU countries, which may require specific privacy protections. However, these tools should be used as part of a comprehensive compliance strategy, not as the sole solution for GDPR requirements.
