Core IP & Network Security Dictionary

Quickly lookup common technical terms and standard definitions used in cross-border e-commerce, global media, and network diagnostics.

Native IP

IP Type

An IP whose RIR registration country (e.g., ARIN, APNIC, RIPE) matches its actual BGP routed location. Enjoy highest trust on platforms like TikTok and streaming services.

Dual ISP Residential IP

Quality

Residential broadband where both ASN type and Organization type are recognized as ISP/Residential. Offers the highest anti-association trust for Amazon and payment gateways.

Residential IP

ISP

IP addresses assigned by consumer ISPs (e.g. AT&T, Comcast) to real households, offering the highest authenticity and lowest risk of being flagged as a proxy.

Hosting / Datacenter IP

Hosting

IP addresses assigned by cloud providers or datacenters (AWS, GCP, Hetzner, Scaleway) to servers. Fast and inexpensive, but prone to blocks on e-commerce and AI platforms.

WebRTC Leak

Security

A vulnerability where browsers communicate via WebRTC and inadvertently expose the user's real public or private IP, bypassing VPN or proxy tunnels.

DNS Leak

Security

When DNS queries are routed outside the encrypted proxy/VPN tunnel to your local ISP's DNS, revealing your true physical location.

Fraud / Risk Score

Risk

A composite risk score (0-100) calculated from blacklist history, hosting flags, Tor/proxy status, and abusive records. Lower scores indicate higher purity.

ASN (Autonomous System Number)

BGP/Network

A globally unique identifier for a connected group of IP networks (e.g. AS15169 Google, AS7922 Comcast) that share a single routing policy.

Anti-detect Browser Isolation

Tooling

Independent spoofing of browser fingerprints (Canvas, WebGL, AudioContext, timezones) paired with residential proxies to prevent multi-account linking.

Broadcast / Anycast IP

BGP Routing

An IP block whose RIR registration country differs from its current active BGP routing destination country. Common in global CDN and cloud deployments.

Frequently Asked Questions (FAQ)

What is Native IP?

Native IP refers to residential or cellular IPs provided by local ISPs where WHOIS data matches the physical location. Compared to data center IPs, Native IPs carry higher trust scores for platforms like TikTok, Netflix, and e-commerce, making them less likely to be flagged as proxies.

How to reduce IP Risk Score?

The key is improving 'purity'. Avoid public proxy pools; instead, use exclusive Residential or Cellular IPs. Also, prevent DNS and WebRTC leaks to ensure your browser fingerprint aligns with your IP's geographic location.

Why does TikTok need Residential IP?

TikTok's anti-fraud system is highly advanced. Hosting IPs are often associated with bot farms, leading to 0-view issues or bans. Residential IPs mimic real household users, significantly reducing risks and improving account stability and content reach.
