Know the baseline first
If a site already answers from the market you are testing, part of your localisation problem is solved before any plan is bought. Checking costs nothing and occasionally removes the requirement entirely.
Free network lookup
Proxy Detector
Paste any website address, pick the market you care about, and see the address that answers for it — exit country, network operator, autonomous system, and whether the traffic lands on hosting infrastructure or a consumer line.
What the Proxy Detector Checks
Every hostname eventually points at an address, and that address says a great deal about how a site is delivered. The tool performs a live DNS resolution over HTTPS, takes the first answering address, and looks up who owns it: the registered country, the city and region on record, the autonomous system number, and the organisation behind that number. It then reads the reverse DNS entry and the authoritative nameservers, because both frequently reveal a content delivery network that the marketing pages never mention.
The last step is a judgement rather than a raw field. The answering operator is compared against known hosting, cloud and edge providers on one side and consumer internet service providers on the other, so the result tells you whether a request is terminating on rented infrastructure or on something that looks like a household connection.
Why This Matters Before You Buy Proxies
Spot the edge network
A hostname sitting behind a large edge provider answers from wherever you happen to be. Recognising that pattern stops teams blaming a proxy vendor for behaviour the destination architecture caused.
Size the requirement honestly
Knowing the autonomous system and the operator behind a target helps you brief a provider precisely instead of asking for the largest pool available and hoping it covers the case.
Where Teams Use It
Marketing and localisation teams run it before commissioning a regional audit, to confirm which markets genuinely serve different content and which simply translate the same page. Engineering teams point it at a target that started failing, because a change of answering operator often explains a change in behaviour more quickly than a log trawl does. Procurement teams use it during an evaluation, comparing what a vendor claims about coverage against what the destinations themselves reveal.
It is equally useful in the opposite direction. Run it against your own domain from a colleague's machine and you will see how your infrastructure presents itself: which edge answers, what the reverse DNS discloses, and whether the registered country matches the market your customers are in.
How to Use the Proxy Detector
- Pick the marketOpen the country selector on the left and choose the market whose experience you want to reproduce. The flag and name shown there become the comparison baseline for the verdict.
- Paste the addressA bare domain works, and so does a full link with a path or query string. Anything after the hostname is discarded before the lookup runs, so nothing private in a URL is sent anywhere.
- Run the detectionPress Detect Proxy. The resolution and ownership lookup usually complete in a second or two, and the status line under the field reports progress or explains exactly what failed.
- Read the verdictThe four summary tiles give exit country, resolved address, operator and autonomous system. Below them, the verdict states whether the answer came from your selected market, and the detail table holds the full record for your notes.
Results describe how a hostname resolves at the moment you ask. Large properties rotate addresses, move between edge providers, and publish different records to different resolvers, so treat a single reading as a snapshot rather than a permanent fact about the destination.
