IP estática vs dinámica
Una IP estática permanece igual en el tiempo, mientras que una IP dinámica es reasignada periódicamente por la red.
La diferencia entre IPs estáticas y dinámicas es la persistencia. Una dirección IP estática permanece fija - el mismo dispositivo o proxy conserva la misma IP indefinidamente. Una IP dinámica cambia con el tiempo, reasignada por el ISP o la red desde un pool cuando expira un arrendamiento o el dispositivo se reconecta.
La mayoría de las conexiones domésticas usan IPs dinámicas: tu router obtiene del ISP una dirección que puede cambiar cada pocos días o al reconectarse. Los servidores y las conexiones empresariales suelen usar IPs estáticas para poder ser alcanzados de forma fiable en una dirección conocida. Ninguna es mejor de por sí - sirven a necesidades distintas.
En el mundo de los proxies, esto se corresponde directamente con los tipos de proxy. Los proxies ISP (residenciales estáticos) te dan una IP residencial fija que no cambia entre sesiones - útil cuando necesitas una identidad consistente durante días o semanas, como al gestionar una cuenta. Los proxies residenciales rotativos dan IPs dinámicas por diseño, asignando una dirección nueva por solicitud o sesión.
Elige IPs estáticas cuando importa la continuidad: inicios de sesión largos, gestión de cuentas o cualquier cosa donde una IP cambiante rompería la sesión o parecería sospechosa. Elige IPs dinámicas/rotativas cuando quieras distribuir solicitudes entre muchas direcciones para evitar límites y bloqueos, como en el scraping de alto volumen.
What makes an address change
A static address is assigned to one customer and stays assigned until someone cancels it. A dynamic address is handed out from a pool for as long as a session lasts, and the next session may get a different one. The distinction is about the lease, not about the technology.
Home connections are usually dynamic because it costs providers less: a household that is offline overnight releases its address to someone else. Business connections are usually static because servers need to be findable and because email and TLS certificates depend on stability.
For proxy work the difference shows up in what a destination site can infer. An address that stays the same across weeks of logins looks like a person with a home and a router. An address that changes every request looks like automation, unless the site expects consumer traffic that naturally rotates.
The corollary is that neither is universally better. Rotation defeats rate limits and spreads load. Stability builds account history. Choosing between them is a question about the target, not about quality.
Which of our products is which
We sell both models, and the choice usually decides itself once you name the task:
Static and dynamic across our catalogue
STATIC ISP proxies from $1.90 per address per month
Datacenter IPv4 from $1.15
IPv6 from $0.20
Mobile modem address holds until you rotate it
DYNAMIC Residential $1.00 per GB, new exit per request
Residential sticky same exit for 30s, 15m or 1h- Account work belongs on static. An account that logs in from one address for months and then keeps doing so is the least interesting thing a platform can see.
- Scraping belongs on dynamic. Spreading requests across many exits is what keeps you under rate limits.
- Mobile sits in between: the address is stable while you leave it alone and changes the moment you ask, which is why it suits account work on platforms that also expect carrier addresses.
- Sticky residential is not static. One hour is the ceiling, and a home device can drop earlier, so anything that must never change belongs on ISP.
Where the terms get muddled
Dynamic does not mean anonymous
A rotating address changes what the site sees between requests. It does nothing about cookies, fingerprints or an account you are logged into.
Static does not mean dedicated
An address can be static and still shared with other customers. Ours are dedicated, but the two words describe different things.
Sticky is not static
It is a dynamic address held temporarily. Building a long-lived account on one is how people lose accounts when the session expires.
Residential is not automatically dynamic
Our residential pool rotates by default, and ISP addresses are residential-registered but static. The registration and the lease are independent.
