Internet Tools
Free online network and internet diagnostic tools — DNS lookup, WHOIS, ping, SSL checker, email security, and more
Network Diagnostics
Ping
Ping any hostname or IP address to check reachability and measure round-trip latency in real time.
Traceroute
Trace the network path to any host, showing each hop's IP, hostname, and latency along the route.
Subnet Calculator
Calculate subnet masks, network/broadcast addresses, host ranges, and CIDR notation for any IP block.
Port Scanner
Scan common ports on any hostname or IP to check which services are open and accessible.
Reverse DNS Lookup
Look up the hostname associated with any IP address using reverse DNS (PTR record) queries.
Website Speed Test
Test the response time and performance of any website or URL. Get TTFB and load time metrics.
DNS Tools
DNS Lookup
Query DNS records for any domain — A, AAAA, CNAME, MX, NS, TXT, SOA, and more record types.
MX Lookup
Find all MX (Mail Exchange) records for a domain and check mail server priorities and hostnames.
NS Lookup
Retrieve the authoritative nameservers (NS records) for any domain. Useful for verifying DNS delegation.
WHOIS Lookup
Look up domain registration details, registrar info, creation date, expiry date, and nameservers.
Email Security
SPF Lookup & Generator
Check your domain's SPF record or generate a new one. Prevent email spoofing and improve deliverability.
DKIM Checker
Verify that your domain's DKIM public key is published correctly. Enter selector and domain to check.
DMARC Lookup & Generator
Look up or generate a DMARC policy for your domain to protect against phishing and email fraud.
BIMI Lookup & Generator
Check or generate BIMI records to display your brand logo in email clients that support it.
Email Blacklist Checker
Check if your IP or domain is listed on major email blacklists (RBLs/DNSBLs) that could block your mail.
Website Tools
HTTP Headers Checker
Inspect HTTP response headers for any URL. Check status codes, cache headers, security headers, and more.
SSL Checker
Verify the SSL/TLS certificate of any domain — check validity, expiry date, issuer, and chain completeness.
Free Online Internet Tools
Our free internet tools cover network diagnostics (ping, traceroute, port scanner), DNS tools (DNS lookup, MX, NS, WHOIS), email security (SPF, DKIM, DMARC, BIMI, blacklist checker), and website tools (HTTP headers, SSL checker). All tools run server-side and require no installation.
