Test the proxy with curl. The check prints the exit IP, not a country; if a lookup of that address names another country, check why location lookups can disagree. For Python configuration and error handling, follow the Requests setup guide.

• A sticky session keeps the same device. The carrier may still change the IP of that device. We do not sell fixed IP addresses on this product, and the pool in the Netherlands is shared.
• A session lifetime is set once per session name with a ttl token, from 60 to 2592000 seconds, and cannot be changed afterwards.
• Mobile traffic runs on carrier modems operated by our network partner; residential traffic runs on opt-in peer devices in the partner network.

Compare rotating and sticky sessions, including why a sticky session can change IP.

• Price and marketplace monitoring

  Read the public price a shopper in the Netherlands is shown, quoted in EUR, together with the delivery and tax lines that come with it. An EU consent banner usually loads before anything else, so allow for it in both your parser and your GB budget.

• Ad verification and brand safety

  Check how a creative renders for an audience in the Netherlands served in Dutch, on a carrier connection, which is how in-app and mobile-web placements are delivered.

• Benelux store-front separation

  Confirm whether your own site, or one you are entitled to check, serves the Netherlands and Belgium the same page, and whether the delivery terms and the currency agree with the country selector.

• QA and geo-testing

  Load your own site from an exit in the Netherlands with Accept-Language: nl-NL, and check the EUR price, the Dutch copy, hreflang, the payment methods offered and any redirect between store fronts.

• AI agents and data pipelines

  Give an agent or a scheduled job an egress in the Netherlands that it selects itself by writing mbl-nl into the username.

We refuse social multi-accounting, sneaker and ticket bots, betting arbitrage, sybil airdrop farming, bonus abuse, credential stuffing, and anything against the law of the Netherlands. Acceptable-use policy · the five use cases in detail

Counts as of 2026-10-08 04:58:37Z, cached for one minute. We never list the exit IPs of a pool.

How do I get a Netherlands IP address?

Buy GB, then put mbl-nl in the proxy username and connect to our gateway over HTTP or SOCKS5: USERNAME-mbl-nl-rot-auto10. The pool is carrier modems in the Netherlands and it is shared between customers; the "modems online now" row at the top of this page is the live count from our stock endpoint, and it is left out when the endpoint does not answer. If no device in the Netherlands is online, the gateway answers 502 with E_NO_STOCK_COUNTRY instead of quietly sending you to another country.

What does Netherlands traffic cost?

The same as every other country: one price list for both pools, EUR 4.50 per GB for a small order falling to EUR 2.50 per GB at the largest step, with the live table on this page. GB never expire. What you buy stays on your balance until you use it; a new purchase adds to the same balance. You can start with 0.5 GB for EUR 2.90, or buy from 1 GB. Payments are accepted in cryptocurrency.

Can I hold the same Netherlands exit for a whole session?

Yes, with a session name: USERNAME-mbl-nl-sid-run1-rot-sticky. The same sid returns to the same device while it is online. A sticky session keeps the same device. The carrier may still change the IP of that device. Set the lifetime once per session with a ttl token, between 60 and 2592000 seconds; it cannot be changed afterwards. Write your job so a dropped device is retried rather than treated as a failure.

Should I use mobile or residential for Netherlands?

The Netherlands is one of the countries where we run both pools, so the choice is one token in the username: mbl-nl or peer-nl. Choose residential when the job calls for a peer-network connection or a country currently available in that pool. Compare the live country lists before planning the job. Switching pools uses the same balance and credential. One balance covers both, so the honest answer is to run the same job twice and compare what comes back.
