What is my IP?
Your public IP, approximate location, ISP, and whether your connection is exposed, behind a VPN, or using a proxy. Loaded in under a second.
Domain inspector
Type any website, get its DNS records, resolved IPs, HTTP reachability, and round-trip latency in one shot. Or keep pinging 9 global servers for live latency.
DNS lookup
Resolve any domain to its A, AAAA, MX, TXT, NS, CNAME, or SOA records via DNS-over-HTTPS. See which resolver answered.
Is it down for me?
Paste any URL to see if it is up for you, or browse live status of 50+ popular services (Cloudflare, GitHub, Discord, OpenAI, Steam, PlayStation, etc.) with 24-hour incident history.
Free SEO checker
Paste any URL and get a 12-point SEO audit in seconds: title, meta description, H1, canonical, Open Graph, image alt text, and more. No signup.
More tools
IP reputation check
Check any IPv4 against 7 major DNS blacklists (Spamhaus, Spamcop, Barracuda, CBL, SORBS, UCEPROTECT, PSBL) plus geolocation, ISP, ASN, and whether the connection looks like a proxy or data center.
Subnet calculator
Paste any IPv4 CIDR (e.g. 192.168.1.0/24) and get the network address, broadcast, first/last usable host, subnet and wildcard masks, total address count, IP class, and full binary breakdown. Pure client-side math.
Email deliverability check
See if a domain is configured to reach the inbox. We query SPF, DKIM (on 20 common selectors), DMARC, MX, and BIMI in parallel and give you a 0-100 score with a list of what to fix.
HTTP headers viewer
Paste any URL and get the full set of response headers plus a 0-100 security grade for the six headers that matter (CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy).
How it works
Every check runs directly from your browser — we don't keep logs, we don't run analytics on your data, and your IP lookups aren't tied to a session. Each request is made by your browser to public DNS, IP-geo, and service status endpoints, and the response is rendered locally.
No accounts. No tracking. No nonsense.
SiteTrace is a small, independent tool built for people who want quick answers without giving up their data. There is nothing to install, nothing to sign up for, and nothing sold to advertisers about you specifically.
Frequently asked questions
What is SiteTrace?
SiteTrace is a small set of free, browser-based network utility tools: a public IP address checker, a ping and latency tester, a DNS record lookup, and a service status checker for 50+ popular sites. No account, no app to install, no data stored on our servers.
Is SiteTrace free?
Yes. All four tools are free to use, with no rate limits, no signup, and no paywall. The site is funded by unobtrusive ads and optional donations via PayPal.
Do I need to install anything?
No. Everything runs in your browser. Open the page, get your answer, close the tab. There is no app, no extension, no plugin, and no download.
Does SiteTrace see what I look up?
No. Your IP lookup, ping test, DNS lookup, and status checks all happen between your browser and the relevant public service. SiteTrace does not sit in the middle, does not log your requests, and does not store the responses.
Can I use SiteTrace from my phone?
Yes. The site is responsive and works on any modern browser. The IP checker works the same on mobile as on desktop, though the ping and DNS tools work best on a stable Wi-Fi or wired connection for accurate results.
