I work with networks every day, and ISP.Tools has been one of my go-to tools for a long time. I use it constantly to run ping, traceroute, MTR, DNS, and HTTP tests from different spots around the internet. Being able to see things from multiple networks makes it way easier to spot routing issues, latency spikes, or reachability problems — no need to rely on other people or wait around for tests. I can see what’s happening in real time.
The platform is super straightforward, and the API comes in handy whenever I need to automate checks or feed data into our monitoring systems. Whenever I want to confirm how traffic is flowing, see how other networks view our ASN, or double-check a route, ISP.Tools gives me quick and clear answers.
Here in Brazil, I’ve seen this tool being used for over eleven years. Every ISP I’ve worked with or talked to uses it — and honestly, I do too, every single day. It’s part of the daily routine for anyone who manages networks around here.
For me, ISP.Tools is simply essential. It helps fix problems faster, saves time, and gives real visibility into what’s going on across the internet.
