Frequently Asked Questions

A:macdetect.com is a comprehensive network toolkit providing MAC address lookup, IP geolocation, subnet calculator, port scanner, traceroute, WHOIS/DNS lookup, and blacklist checker tools. All tools are free to use and designed for network administrators, IT professionals, and anyone needing network diagnostic capabilities.

A:Yes, all our tools are completely free to use with no registration required. We support our service through non-intrusive advertising.

A:No account is required to use our tools. You can access all features immediately without registration.

A:A MAC (Media Access Control) address is a unique identifier assigned to network interfaces. It's a 48-bit address usually displayed as six groups of hexadecimal digits (e.g., 00:1A:2B:3C:4D:5E).

A:Our database contains official IEEE OUI assignments and is regularly updated. The manufacturer information is highly accurate, though some newer or private assignments may take time to appear in our database.

A:Yes, we support all common MAC address formats including colon-separated (00:1A:2B), hyphen-separated (00-1A-2B), dot-separated (001A.2B3C), and no separators (001A2B3C4D5E).

A:We update our database regularly to include new IEEE OUI assignments. You can check the last update date on the homepage.

A:We provide IP Geolocation (location finder), IP Subnet Calculator (IPv4/IPv6), Port Check (port scanner), Traceroute (network path analyzer), and Blacklist Checker (email reputation).

A:IP geolocation accuracy varies by region and can range from country-level to city-level precision. It's based on network infrastructure, not physical device location.

A:Yes, our Port Check tool supports bulk scanning. You can select multiple common ports or enter custom port numbers (up to 100 ports per scan).

A:TCP is connection-oriented and provides reliable delivery, while UDP is connectionless and faster. Our tool supports both protocols with accurate status detection (open, closed, filtered, timeout).

A:Traceroute shows the path packets take from your computer to a destination server. It displays each hop (router) along the way with latency measurements, helping identify network issues and routing problems.

A:Some routers are configured not to respond to traceroute probes for security reasons. This is normal and doesn't necessarily indicate a problem unless all subsequent hops also timeout.

A:WHOIS lookup provides domain registration details including registrar, registration date, expiration date, nameservers, and domain status. Note that many registrars now use privacy protection to hide owner details.

A:Yes, our WHOIS/DNS tool shows various DNS records including A, AAAA, MX, NS, TXT, CNAME, and SOA records for any domain.

A:An IP blacklist (DNSBL/RBL) is a database of IP addresses identified as sources of spam or malicious activity. Email servers use these lists to filter incoming mail.

A:We check your IP against 10+ major blacklist databases including Spamhaus, Barracuda, SpamCop, SORBS, and others commonly used by email providers.

A:First, identify and fix the issue that caused the listing (compromised accounts, malware, etc.). Then visit the blacklist provider's website to request removal. Each provider has different procedures.

A:If you run an email server, check weekly. If you notice deliverability issues, check immediately. Regular monitoring helps maintain good sender reputation.

A:We respect your privacy and do not store or log individual search queries. We only collect anonymized usage statistics to improve our service.

A:Currently, we offer web-based tools. API access may be available in the future for enterprise users.

A:Our tools work on all modern browsers including Chrome, Firefox, Safari, Edge, and mobile browsers. We recommend keeping your browser updated for the best experience.

A:Our tools are designed for web browser use. Automated scraping or excessive requests may be rate-limited. Please contact us if you need bulk access.

A:We implement industry-standard security measures including SSL/TLS encryption, secure data storage, access controls, and regular security audits. See our Privacy Policy for details.
