DNS lookup, IP address conversion (IPv4 / IPv6 / decimal / binary), and other essential network utilities for developers, sysadmins, and curious users.
Whether you're configuring a domain, debugging a connection, learning how the internet works, or just wondering what your IP address looks like, Tooloogle's Network Tools category gives you fast, browser-based utilities for everyday networking questions — no command-line, no installations, no signups.
Look up A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, and SRV records for any domain. Useful when you're setting up email (verifying MX and SPF/DKIM), migrating hosts (checking nameserver propagation), debugging why a site won't load, or auditing a domain's configuration.
Convert IPv4 addresses between dotted-decimal (192.168.1.1), decimal (3232235777), binary (11000000.10101000...), hexadecimal (0xC0A80101), and octal forms. Convert IPv6 between full (2001:0db8:0000:0000:0000:ff00:0042:8329) and compressed (2001:db8::ff00:42:8329) notations. Useful for firewall rule writing, network classroom homework, log-file analysis, and CIDR calculations.
Most online "what's my IP" sites are slow, ad-heavy, or log your queries. Most desktop network utilities require installing CLI tools like dig, nslookup, or traceroute. Tooloogle's tools sit in the middle: each one runs entirely client-side for conversions (your IP entries never leave the page) and uses Google's free public DoH endpoint for live DNS queries (no tracking, no caching abuse). You get authoritative answers in a clean UI without spinning up a terminal.
Sysadmins & DevOps engineers verifying DNS changes during deploys.
Web developers debugging CORS, CDN, or SSL issues that trace back to DNS.
Email administrators validating SPF, DKIM, DMARC, and MX records.
Students learning networking fundamentals (CCNA, Network+, computer science).
Security researchers doing initial reconnaissance on a domain.
Curious users who just want to know what their IP is or whether a domain is set up correctly.
IP conversions happen entirely in your browser; nothing is sent to any server. DNS lookups use Google's public DNS-over-HTTPS endpoint, which is anonymous and respects standard caching headers — results are authoritative and match what dig would return from any major resolver.
Pick the tool you need or explore a few side-by-side — many networking workflows (debugging email delivery, for instance) chain two or three of these together.
