Networking tools provided as a public service by hq42.net

Read the HQ42 FAQ, it will help you to quickly become familiar with these tools.

All of these tools have restrictions governing the input they will accept.
Two types of input are acceptable "dotted-quads" that is standard IP addresses like 38.103.63.57
and also simple host names like www.yahoo.com, no http:// or other protocol prefixes are allowed for security reasons.
You may not specify a port for any of these tests, except the "NON Standard Ports" tool. The tests default to the standard port for the service.
