Online Ping — Check Host Availability

The Online Ping tool at 101IP lets you instantly check the availability of any IP address or domain. Enter a host and get response time, packet loss and status without installing any software.

What Ping shows

• Response time (ms) — how quickly the host replies to a request;
• Min / Avg / Max — spread across 4 requests;
• Packet loss — percentage of requests that got no reply;
• IP address — the actual IP the domain resolves to.

When is Online Ping useful?

• checking whether a website or server is currently up;
• diagnosing packet loss and connection instability;
• measuring latency to a CDN or external API;
• quick diagnostics without terminal access.

If ICMP is blocked by a firewall, the tool automatically falls back to a TCP test on port 443, 80 or 22.
