Net tools

Domain availability, DNS & IP lookups.

• Request Echo — See what the server actually received: every header, the real IP, the proxy chain.
• HTTP Testbed — Return any status, delay, redirect or payload size to exercise client retry and timeout logic.
• Webhook Box — Generate a temporary URL to capture third-party callbacks and inspect headers and body in full.
• IP Check — See every exit IP at once — mainland, international, Cloudflare edge and server-side viewpoints probed in parallel with an automatic split-routing verdict, cross-checked across five geo providers, plus WebRTC / timezone / IPv6 leak checks.
• Speed Test — Multi-threaded speed test: parallel connections measure download and upload throughput, HTTP round-trip latency and jitter, with each connection's contribution shown — a lagging stream usually means packet loss or a rate-limiting middlebox.
• Domain Check — Check domain availability.
• DNS & IP — Look up DNS records & IP info.
• Subnet Calculator — IPv4 CIDR subnet calc: network, broadcast, mask, hosts.
• SEO Audit — On-page SEO audit with per-check fixes; deep scan adds Lighthouse + broken-link detection.
