Count stable identities, not requests. One IP per account, client, location or allowlist, then add spares.

**Quick answer — How many static IPs do I need?**

How many static IPs do I need? Count one IP per identity that must stay stable: per business account, per client, per location you check from and per allowlist source. Then add about one spare for every ten IPs. **SteadyProxy** sells 1, 5, 10, 25, 50 or 100 ISP IPs per order; 10 ISP IPs cost $20.86 for 30 days as of October 2026.

## What are the counting rules?

| Attribute | Value |
| --- | --- |
| Accounts | One IP per business account or client that logs in from a fixed IP |
| Locations | One IP per country or city you check from |
| Allowlists | One IP per source system, plus one backup IP |
| Spares | About one spare per ten IPs in use (our planning advice) |
| ISP plan sizes | 1, 5, 10, 25, 50 and 100 IPs |
| Datacenter plan sizes | 1, 10, 25, 50 and 100 IPs |
| Volume price | Per-IP price never rises with quantity; down to $1.34/IP · 30 days at 100 ISP IPs |

## How do I count static IPs for business accounts?

Give each account its own IP and keep that pairing for as long as the account exists. That way each account shows one stable address in its login history, and a problem on one IP touches one account only. This applies to your own brands, to the accounts of agency clients who hired you, and to your own marketplace seller accounts. Do not share one IP between accounts that belong to different clients. The [social media agencies page](https://steadyproxy.com/use-cases/social-media-agencies/) shows this setup in more detail.

## How many IPs do I need for local price, ad or search checks?

Count locations, not queries. One static IP in a city can run many light checks per day for that city, spread over hours. If you check 5 cities, start with 5 IPs. Add a second IP per city only when the volume per IP becomes high for the target sites, or when you need a backup. Respect each site's terms and rate limits. For rank tracking from a fixed place, see the [SEO monitoring page](https://steadyproxy.com/use-cases/seo-monitoring/).

## How many IPs do I need for IP allowlisting?

Two per destination is a safe minimum: one in daily use and one backup already on the allowlist. If the main IP fails or is replaced, traffic moves to the backup without a new approval. Several systems behind one firewall can share the same pair. The [allowlisting guide](https://steadyproxy.com/guides/ip-allowlisting/) walks through each step. For pure allowlisting, a [dedicated datacenter IP](https://steadyproxy.com/datacenter-proxies/) at $1.34 for 30 days is often enough.

## Worked example: how many IPs does an agency with 18 clients need?

*Example only. 25 IPs match the 25-IP plan: $50.46 for 30 days, as of October 2026.*

| Need | Rule | IPs |
| --- | --- | --- |
| 18 client business accounts | One IP per account | 18 |
| Local price checks in London, Berlin and Paris | One IP per city | 3 |
| Allowlisted access to the agency's own reporting server | One main IP + one backup | 2 |
| Spares | About one per ten IPs in use | 2 |
| Total |  | 25 |

## Should I mix ISP and datacenter IPs?

Yes, when tasks differ. Use ISP IPs where the ISP network name helps, such as consumer-facing local checks or account logins. Use dedicated datacenter IPs where only a fixed address matters, such as allowlists and internal tools. As of October 2026, one ISP IP costs $2.24 and one datacenter IP costs $1.34 for 30 days. Availability differs by country. Availability varies by country; the checkout shows what is online.

## What else do people ask about IP counts?

### Can several accounts share one static IP?

Technically yes, but separate IPs are cleaner. Accounts of one owner and one team can share an IP if the platform allows it. Accounts of different clients should not: one problem would then affect several clients. When in doubt, one IP per account is easy to reason about and easy to audit.

### Is it cheaper to buy one large plan or several small ones?

Compare totals. The per-IP price never rises with quantity: one ISP IP costs $2.24, ten cost $20.86 and one hundred cost $133.88 for 30 days, as of October 2026. For a count between two plan sizes, add the totals of the plans you would combine and compare them with the next larger plan before you pay.

### How many spare IPs should I keep?

About one spare for every ten IPs in use is our planning advice, and at least one for any allowlist. A spare lets you move an account or a job at once when an IP has a fault, while support handles the repair. It is not a measured failure rate; adjust it to how costly a pause is for you.

### Do I need more IPs for more traffic?

Not usually, because billing is per IP and not per GB. Billed per IP and per 30 days, not per GB; fair use applies. Add IPs when a target site limits the requests one IP may send, or when you need more locations. For high-volume public-data collection without logins, rotating proxies may suit better; see [keep or rotate](https://steadyproxy.com/guides/keep-or-rotate/).

### Can I add IPs later without changing the existing ones?

Yes. Each order adds new IPs with their own 30-day rental; existing IPs keep running until their own end dates. New IPs may come from other ranges. Several IPs in one order can share the same /24 subnet; subnet diversity is not guaranteed. Note which order each IP belongs to, so renewals do not surprise you.

### Do I need IPs from different subnets?

Only if one range-wide block or outage would hurt you. IPs in the same /24 can be limited together by some sites. If that risk matters, spread IPs across countries or orders and count your subnets after delivery. Our [subnet diversity guide](https://steadyproxy.com/guides/subnet-diversity/) has a script that counts them.
