BIT HAPPENS // DIAGNOSTIC

NETWORK
DIAGNOSTIC.

Enter a domain or IP. The diagnostic combines public queries and controlled external tests, shows where each piece of evidence comes from and generates local commands to dig into what the browser cannot measure.

01 // TARGET

Diagnostic target

READY
ABUSE PROTECTION //

The active port test only runs after the automatic Cloudflare Turnstile validation.

PRIVACY

Private hosts, localhost and .local names are never sent to public services. TLS/HTTP and light TCP checks run on the portal infrastructure; a full Nmap scan stays limited to authorized flows.

TARGET

Normalization

WAITING
Enter a target to start.
02
DNS

Public resolution

WAITING
A, AAAA, MX, NS and TXT for domains; PTR for IPv4.
03
RDAP

Registration and network

WAITING
Domain registration or the block responsible for the IP.
04
GEO / ASN

Public IP

WAITING
Approximate location, ISP and ASN of the first public IPv4 found.
05
HTTP / HTTPS

Application and HTTPS evidence

WAITING
HTTP/HTTPS response and observable headers. The runtime exposes neither the peer certificate, the negotiated TLS version nor the cipher; Certificate Transparency data is historical context only.
06
PORTS / SERVICES

Exposed services

WAITING
Quick external test of common ports with service and risk interpretation.
07
TRACEROUTE

Route and map

WAITING
Run traceroute on your machine and paste the output here, or compare with the route seen from probes on other networks.

Frequently asked questions

What does Network Diagnostic check?

For a domain or IP, it queries DNS, RDAP and ASN, tests the HTTP and HTTPS response, checks common ports and prepares the traceroute. Each block shows where the evidence came from and what still needs to be confirmed on your network.

Why is the result different from what I see on my computer?

The external tests run from the Bit Happens infrastructure, not from your network. A firewall, VPN, local DNS or CGNAT can make the same target answer differently for you. Use the suggested commands to compare.

Does an HTTPS timeout mean an invalid certificate?

No. A timeout means the connection did not complete in time, because of a firewall block, a service down on port 443 or the wrong hostname. A certificate problem shows up as a TLS error, not as a timeout.

Can I diagnose an IP or host on my internal network?

Not through the portal. Private addresses, localhost and .local names are never sent to external services. For them, run locally the commands the diagnostic generates.

Is the port test safe for the target?

It only tries to open a TCP connection on a few common ports, without reading banners or trying to authenticate. Even so, use it only on assets you manage or are authorized to test.
