Needle

Reachability probes from your browser

Idle

Test one hostname, domain, or IP on every port in the ports list.

IP range

Inclusive range. Max 256 hosts (HTTP on each selected port).

Range scan only: opens up to max parallel tabs (one host each). Each tab probes its host with the same max parallel setting, then closes automatically.

Comma-separated ports. Each port gets one liveness probe first; favicon paths are only tried on open ports. 443 and 8443 use https.

Opens http://N.atnalam.ai (public DNS stays on Needle). Shows Pending IP switch until your hosts file maps that name to 10.100.102.N. Image tests (iframe / img / object / embed / xhr) then run on that host — never https://10.100.102.N from this page. Example: 1.atnalam.ai or 10.100.102.1.

Live hosts

Use Test or Scan range to run probes.

No live hosts yet.
