ISP Proxies in South Korea
Datacenter-hosted IPs announced under real residential ASNs. Stable, persistent, and the right tool when cookies and session state need to survive across a multi-turn evaluation or a sustained RAG ingestion.

Why ISP exists between residential and datacenter
ISP proxies are datacenter-hosted IPs that have been announced under a real residential ASN. You get the persistence and latency of datacenter with the ASN reputation of residential. The trade-off: no diversity — you have a specific, stable set of IPs assigned to your account.
For AI workloads, ISP is specifically useful when:
- A multi-turn agent evaluation depends on the same IP across a long conversation, because mid-session IP rotation breaks session cookies, CSRF tokens, and some chat-history features on commercial APIs
- A RAG ingestion pipeline logs into a knowledge source (with permission) and the source's rate limiter is per-IP
- You need sub-50ms latency to a US or EU eval target but the target ASN-classifies AWS subnets and downgrades you
Where ISP is wrong
- SquadProxy diversity. A training-corpus workload sampling broadly from the open web does not benefit from ISP's persistence. Use residential or datacenter instead.
- Mass parallel evaluation. Running 50k concurrent eval requests from 100 ISP IPs means 500 requests per IP — which is not residential-shaped behaviour even though the IP has a residential ASN. Mix with rotating residential above scale.

Korea, Canada, Netherlands, and Australia ISP allocations available on request but are smaller pools. Ask before quoting.
Provenance
ISP announcements are done through upstream partnerships with carriers that lease residential IP space. Every allocation has a RIR-visible ownership chain ending at the carrier. For customers publishing model cards or data cards that have to disclose source infrastructure, this is documentable.

FAQ
South Korea ISP FAQ
Are these really ISP proxies in South Korea?
Yes — the exits in this pool announce from the South Korea ASNs we list on the country page (KT (AS4766), SK Broadband (AS9318)) and route through our Asia edge. You can verify ASN and carrier on every request.What session lengths can I hold on South Korea ISP?
Per-request rotation is the default. Sticky sessions are supported up to 60 minutes via the X-Squad-Session header. For anything longer, use our ISP pool instead.Is targeting down to a city available on South Korea ISP?
Yes, via X-Squad-City. Pool depth varies by city — the deepest are Seoul, Busan, Incheon. Smaller cities are served but have thinner concurrency.Any legal or compliance notes specific to South Korea?
South Korea governs data collection under the Personal Information Protection Act (PIPA), substantially revised in 2023 to add automated-decision rights and tighten cross-border transfer rules. The Copyright Act contains a TDM exception in Article 35-5 added in 2022, narrower than the Japanese Article 30-4 equivalent — notably requiring that the purpose be non-recreational and not unreasonably prejudice rights-holders' interests. The Act on Promotion of AI (2025 legislative cycle) is tracked by the PIPC. Enforcement precedents around training-data collection are still developing, but scraping of personal data without lawful basis has attracted administrative penalties.
