Look up DNS records, find out who owns an IP address or a domain, check an SSL certificate, test a port or a mail server, check blacklists and see whether a site is up from outside your own network. [Open Network Tools](https://net.openvibe.tools/) ## 38 tools These tools answer the questions that come up when something on the internet does not work: where does this domain point, why is mail bouncing, is the certificate about to expire, is the site down for everyone. Each one takes a domain, an IP address or a URL and gives a readable answer in a few seconds.

No. Every lookup runs from our servers and the result appears in your browser, so the tools work on a phone, a locked-down work laptop or a Chromebook. Where do the lookups run from? Every check runs from the OpenVibe server, outside your own network. Ping and latency are timed TCP connections; traceroute and MTR send ICMP echo hop by hop (mtr). Can I check a server inside my own network? No. The checks come from the public internet, so the target has to be reachable from outside your network. ## The rest of OpenVibe 5 links One account works on every site.
