Checking their own sites for the language, redirects and legal notices a market is served, none of which is visible from an office in a different market.
Sites change what they serve by country: prices, stock, currency, language, consent banners, whole redirect chains. Testing that from your own desk measures your own market. A static address in the target country turns a guess into an observation you can repeat.
The catalogue covers 73 countries and names the provider behind every block. It says what the catalogue carries, not where we have personally tested delivery.
In short: Region testing means checking a site from inside the market you are asking about, so that what you record is what a visitor there is served. Unless a visitor grants location permission, a site has to infer where they are, usually from the IP address — so a static address in that country, kept between runs, is what makes a week-on-week comparison mean something.
The address you test from is registered to an internet provider in the country picked at checkout, and nobody else uses it while the period runs. Prices, currencies, stock, delivery options and legal notices all change by country, and none of those changes is visible from an office in a different market.
A browser shares a precise location through the Geolocation API, and the W3C specification requires express permission from the user before any location is shared. A site that never asks falls back on the address, using geolocation data that networks can publish for their own address blocks in the geofeed format of RFC 8805. Language is a separate signal: the browser states its preference in the Accept-Language header (RFC 9110, section 12.5.4), so a test that moves the address but not the language setting can show local prices in the wrong language. The advice here follows from those mechanisms rather than from measuring any particular site.

Comparing what different markets are offered, from a fixed vantage point so a difference between two runs means something changed.
The table below is a starting set.
Keep it for as long as the comparison runs.
With the language and time zone set to the market’s.
A screenshot, the final URL after redirects, and the price and currency as shown.
Compare with the baseline rather than with your own office view.
Load what is my IP through the address and confirm it still geolocates to the market. If it has moved, ask for a replacement instead of filing the result.
| What changes | How you notice it is wrong | |
|---|---|---|
| Price and currency | The number, the symbol, and whether tax is included | Your screenshot does not match the customer's invoice |
| Stock and availability | Which items and plans are offered at all | Support answers a question about a product nobody there can see |
| Language and locale | Copy, date order, decimal separators, address forms | A form rejects a valid local postcode |
| Consent and legal notices | Which banner appears and what it must ask | A market complains about a notice you never saw |
| Redirects and routing | Which domain or subfolder you land on | Analytics shows traffic entering somewhere you did not build |
| Search and recommendation | Ranking and suggestions tuned to the market | Two people describe the same page differently |
A test is only useful if two runs differ because the site changed, not because you arrived from a different network. One address per market makes the vantage point a constant instead of a variable you forgot you had.
Some sites treat addresses registered to hosting companies differently from other connections — a challenge page, a generic version, or nothing at all. An address registered to an internet provider is not screened as hosting, which takes that variable out of the test.
Carts, sessions, A/B assignments and cookie choices all live against an address. Rotation resets them mid-run, and a test that keeps resetting is testing your proxy rather than your site.
No. The static residential catalogue is sold by country, provider and plan, and no offer in it today is tied to a city or region. Some addresses will of course be registered in one place rather than another, but that is a property of the block you were given, not a setting you can request — and a page that implied otherwise would be describing a control we do not have.
The catalogue carries 73, each with the provider named. Testing several markets means one address per market: they are priced per IP per period, so a five-market test is five addresses rather than a plan with a country switch on it.
It depends what varies. Prices, stock and redirects are usually visible to a plain request. Consent banners, client-side geolocation and anything rendered after load need a real browser, and a browser will also ask for permissions and read a time zone that should agree with where you claim to be. The address is one input among several; making the rest agree with it is your side of the job.
A consumer VPN puts you on an address shared with everyone else using that endpoint, and one that a site's geolocation or risk data may already mark as a VPN. That is fine for reading a news site and poor for measuring one, because you cannot tell whether what you are seeing is the local experience or the experience that kind of address gets. A dedicated address removes the ambiguity.
Not during the period you paid for, and not when you renew. That is what makes a week-on-week comparison mean something: the only variable that moved is the thing you were testing.
An address that starts resolving to a different country is explicit grounds for a free replacement, up to 20 % of the order per calendar month. For this scenario it is the failure that matters most, because a test bench quietly moved to another country produces confident, wrong answers rather than obvious ones. Terms of Service
