Two kinds of addresses, two very different reputations
A mobile IP and a datacenter IP can look interchangeable: in both cases your traffic exits from another address. In practice, sites treat them very differently. Here is why, and when each one makes sense.
Two types of address, two reputations
An IP address is not neutral. It belongs to a block registered with a regional registry, and that block is labelled: hosting provider, mobile carrier, fixed-line carrier, company, university. The label is public and free, and any site can look it up in one request.
Datacenter addresses (OVH, Scaleway, AWS, Hetzner, DigitalOcean and others) are therefore identified as servers before a single line of HTML is generated. Mobile addresses belong to Orange, SFR, Bouygues or Free and are associated with subscribers. The difference in how anti-bot systems treat them flows directly from that label.
Factual comparison
| Criterion | Datacenter IP | 4G/5G mobile IP |
|---|---|---|
| Public label | Hosting provider | Mobile carrier |
| Block rate on French sites | High | Low |
| Typical latency | 5 – 30 ms | 20 – 80 ms |
| Address stability | Very stable | Natural rotation |
| Throughput | Very high | 20 – 150 Mbit/s |
| Monthly cost | Very low | A few times higher |
| UDP and all protocols | Yes | TCP (HTTP, SOCKS5) |
| Geolocation | Precise (datacenter city) | Regional or national |
Why a mobile IP gets through where a server IP fails
Three mechanisms combine. First, the static blocklist: many protections ship with lists of known hosting ranges. Second, behavioural detection: a datacenter address chaining 500 requests in ten minutes is a strong signal. Third, historical reputation: a datacenter range is regularly used by bots, and its reputation degrades collectively.
A mobile range is structurally shared between thousands of human subscribers. Blocking an entire mobile range means blocking the customers of the carrier, so sites do it sparingly, and usually at account level rather than address level.
Where datacenter still wins
It would be dishonest to claim otherwise. A datacenter IP costs less, offers more bandwidth, lower latency, perfect stability and support for every protocol including UDP. For querying a tolerant public API, downloading bulk data, hosting a service or uptime monitoring, it is the right choice.
So the question is not which one is better, but what does my target filter? If it filters hosting providers, no amount of code optimisation will compensate: you need an address of a different kind.
The myth of the residential mobile IP
You often read that a mobile IP is the best residential IP. That is loose language. A residential IP belongs to a fixed line, fibre or DSL, and is often tied to an identifiable household. A mobile IP is shared dynamically between thousands of users through carrier CGNAT: it is less attributable to one person, but it also changes more often.
For French audiences the winning combination is usually a mobile address for consumer sites and sensitive platforms, and a datacenter address for everything else. A good collection tool can route selectively depending on the target.
What this means for your budget
A sensible architecture does not allocate a mobile IP to everything. Reserve it for the requests that need it, usually 10 to 30% of total traffic, and let the rest go through a datacenter. You cut the bill without degrading the overall success rate.
With us that means a low entry tier, per-gigabyte top-ups and no throttling, so the maths stays simple. To see how these addresses are produced, read our page on the French mobile proxy; for the pace of rotation, read the article on IP rotation.
