Compare marketed ISP proxies vs residential proxies: when residential (especially static) is usually enough, and how marketing "ISP" differs from static residential. ZTProxy sells residential only (GB rotating / IP-month static). Confirm prices in the console. Not for mainland China.
First: which layer are you comparing?
“ISP vs residential” is often mixed with two other layers:
- Exit / marketing type: traffic leaves via a home-broadband residential peer, or via a product marketed as ISP / static ISP (often sold as a relatively fixed exit under an ISP ASN).
- Session rhythm: how long the same exit must stay—covered in Rotating vs static residential and Sticky session vs static IP.
- Other exit-type axes: datacenter in Residential vs datacenter; mobile in Residential vs mobile. This page completes the ISP vs residential corner.
Marketing that says “ISP is always the stronger static” often collapses those layers. This page only clarifies marketed ISP vs residential. If you already know you need residential, go to the buyer checklist or zt-01 next. Lawful, authorized, and public-data use only. Not supported for use in mainland China.
What residential proxies are
Residential proxies forward requests through addresses assigned by home broadband ISPs. The origin looks closer to ordinary household or office broadband users than to typical hosting ranges or mobile-carrier ranges.
On ZTProxy, the residential line includes:
- Rotating residential: billed by GB; exits can rotate (optional short sticky sessions)
- Static residential: billed by IP × month; relatively fixed exit for the term (shared / dedicated)
List prices: Pricing (about $0.40/GB; shared about $1.50 and dedicated about $5 per IP month, etc.). Console is source of truth. Regions: Locations—inventory changes.
What marketed “ISP proxies” usually mean
Industry names like ISP proxy / static ISP / ISP residential are not standardized. A common marketing meaning is: exits under an ISP-registered ASN, biased toward a relatively fixed identity (often long lease, billed per IP). That is not “stronger rotating residential,” and it is not automatically the same as this site’s static residential product—definitions, hosting, and contract wording differ by vendor.
Important: This article does not describe ZTProxy as selling a separate ISP / static ISP SKU, and it invents no ISP price list or inventory. The on-site static product page says static residential and does not label the SKU as ISP—so do not treat “static residential” as automatically equal to competitors’ marketed “ISP.” If a purchase order or target policy explicitly requires an “ISP”-labeled product, read that vendor’s product page or evaluate another supplier; this site focuses on residential proxies. The tables below help decide “is residential enough?”—they are not an ISP checkout page.
Side-by-side comparison
| Dimension | Residential proxies (this site) | Marketed ISP proxies |
|---|---|---|
| Exit intuition | Home-broadband ISP address (peer); rotating can change; static is relatively fixed for the term | Often emphasizes ISP ASN / “static ISP” branding; fixity and hosting vary by vendor |
| Typical fit | Public multi-region sampling, localization/ad self-checks, authorized store identity for the term | Buyers whose brief explicitly requires an “ISP”-labeled product (subject to policy and compliance) |
| On ZTProxy | Rotating (GB) / static (IP×month) | No separate ISP SKU on this site (do not look for ISP checkout here) |
| Relation to “static residential” | Static residential = term-long fixed exit under the residential line | Static residential ≠ automatically marketed “ISP” (unless a product page says so; this site currently does not) |
| Bill intuition | Rotating often per GB; static often per IP×month; see Pricing | ISP often per IP×month / long lease—follow each vendor; do not invent an on-site ISP quote |
| Sticky relation | Rotating can open a short sticky window; sticky ≠ term-long static | Do not confuse “ISP” with sticky sessions |
| Limits | Cost and inventory constraints; still must follow law and target terms | Naming is messy; opaque ASN/hosting details cause wrong buys; no guaranteed site outcomes |
No success-rate, SLA, or inventory promise.
Choose by task
| Task | Common lean | Note | Next |
|---|---|---|---|
| Public product/price/ad page sampling, multi-region checks | Residential · rotating | Many exits + per GB usually enough | Rotating · Price monitoring |
| Localization language / checkout self-check | Residential · rotating (sticky for short flows) | Sticky window follows console | Localization testing · Sticky vs static |
| Authorized store admin; same exit for the term | Residential · static | Stability first; then shared/dedicated | Static · zt-01 |
| Ecommerce: research rotating, store static | Residential · split by task | Do not replace product split with “just buy ISP” | Ecommerce |
| PO / brief explicitly requires an “ISP”-labeled product | ISP-marketed class may be needed | No separate ISP checkout here | Evaluate another vendor or read their product page; do not invent a ZTProxy ISP plan |
| Still unsure residential vs datacenter | Read zt-14 | Other exit-type axis | Residential vs datacenter |
| Still unsure residential vs mobile | Read zt-16 | Third exit-type axis | Residential vs mobile |
| Residential chosen; unsure rotating vs static | Read zt-01 / zt-15 | Type → rhythm → billing | Rotating vs static · Buyer checklist |
Short cases (illustrative, not promises)
Weekly public competitor price checks. Rotating residential billed by GB is a common fit; smoke-test small. Scene: Price monitoring.
Authorized cross-border store admin. Need a term-long fixed exit → start with on-site static residential. Do not assume this site is “missing ISP” just because a competitor uses that word—confirm whether you need the label “ISP,” or simply a stable residential exit.
The purchase order says “ISP proxy” only. Read the vendor’s product definition. Do not look for a fictional ZTProxy ISP SKU here, and do not frame the need as evasive multi-login or platform-policy workarounds.

Pre-order checklist
- Does the task require a product explicitly labeled ISP on the purchase page? If not, evaluate whether residential is enough.
- If residential: rotating or static? → zt-01; short same-exit window → Sticky vs static first.
- Do not assume “static residential = ISP”—follow the static product page and console copy.
- Is the region confirmable on Locations + console?
- Lawful, authorized or public-data use; not mainland China.
- Credentials follow the console; connect via Docs EN quickstart.
- Smoke-test small, then scale.
FAQ
What is the difference between ISP proxies and residential proxies?
Naming differs: “residential” emphasizes a home-broadband peer exit profile; marketed “ISP” often emphasizes an ISP ASN and a relatively fixed exit—but vendors define terms differently. Read product-page fields, not only the title word. Choose type before rotating/static.
Is static residential the same as an ISP proxy?
Not necessarily. On-site static residential is a term-long fixed exit under the residential line; the product page does not label it ISP. Competitor “ISP” offers may mean different hosting and contract wording. If you need the “ISP” label, follow that vendor’s page—do not assume equivalence.
For public collection and multi-region testing, is residential enough?
For many public-page samples and ad/localization self-checks, rotating residential billed by GB is a common match—validate at small volume first. Scenes: Price monitoring, Ad verification, Localization testing.
Does ZTProxy sell ISP proxies?
This site focuses on residential (rotating / static). This page provides no separate ISP SKU or price list; if you need an explicitly ISP-labeled product, evaluate another vendor or read their product page.
Is ISP always “better” than residential?
No. There is no absolute “better”—only fit for task, budget, compliance, and target policy. Avoid absolute ranking-style conclusions.
Is a sticky session an ISP proxy?
No. Sticky is a short same-exit window on residential rotating products; it is unrelated to marketed ISP product classes. See Sticky session vs static IP.
After I choose residential, what do I buy next?
Open rotating or static, confirm rhythm and billing with zt-01 and the buyer checklist, then Pricing. Other exit-type axes: datacenter, mobile.
Can I use this in mainland China? Can I pay with a credit card?
No for mainland China use. Public notes include crypto (e.g. USDT/USDC). Visa / Mastercard are applying / pending. Regions/inventory: Locations + console. List prices: Pricing; role price and charges follow the console.
