Checking server IP reachability

To confirm that your Web Hosting, VPS, or dedicated server IP is reachable from different parts of the world, use a Looking Glass service.

Looking Glass tools let you run traceroute or ping tests from remote servers located in various countries and networks — this helps identify routing issues, blocks, or connectivity problems.

You can find your server's IP address in your personal account → IP Addresses section.

How to run a reachability test

1. Go to any public Looking Glass service, for example:

   • lookinglass.org
   • bgp.tools
   • You can also use our Looking Glass service.

2. Enter your server's IP address and start a traceroute or ping test. Example of successful traceroute output:

traceroute to 212.224.124.82 (212.224.124.82), 30 hops max, 60 byte packets
 1  Juniper_PTX10016.local  0.425 ms
 2  Cisco_NCS_5500.local  5.338 ms
 3  10.109.11.125  11.085 ms
 4  *
 5  212.188.6.44  5.192 ms
 6  *
 7  212.188.42.42  5.332 ms
 8  212.188.42.121  5.723 ms
 9  212.188.55.2  5.087 ms
10  212.188.0.33  7.166 ms
11  212.188.55.25  24.511 ms
12  212.188.42.120  7.117 ms
13  212.188.56.143  7.095 ms
14  212.188.2.53  19.289 ms
15  212.188.29.109  72.394 ms
16  80.81.194.3  46.476 ms
17  212.224.104.3  45.977 ms

• If the trace reaches your IP and latency is reasonable (usually under 100–150 ms), your server is reachable from that location.
• If the trace stops with many asterisks (*) or times out — there may be a routing issue, provider filter, or block along the path.

What to do if the server is unreachable from some locations

1. Compare results from multiple Looking Glass servers (Europe, US, Asia, etc.).
2. If the server is reachable from most locations but not from your home/office network:

• Find your public IP address using one of these services:

  • whatismyipaddress.com
  • ifconfig.me
  • showmyip.com

• Run the same traceroute/ping test against your own IP from Looking Glass.

• If your IP is also unreachable — the issue is likely with your ISP. Contact their support and provide the traceroute results.

3. If the server is unreachable from many locations worldwide:
   Open a ticket in support and include:

• Your server IP address
• Which Looking Glass server you tested from
• Type of test (traceroute or ping)
• Screenshot or copy of the output
