-# FakeIP
-
-FakeIP refers to a type of behavior in a program that simultaneously hijacks both DNS and connection requests. It
-responds to DNS requests with virtual results and restores mapping when accepting connections.
-
-#### Advantage
-
-* Retrieve the requested domain in places like IP routing (L3) where traffic detection is not possible to assist with routing.
-* Decrease an RTT on the first TCP request to a domain (the most common reason).
-
-#### Limitation
-
-* Its mechanism breaks applications that depend on returning correct remote addresses.
-* Only A and AAAA (IP) requests are supported, which may break applications that rely on other requests.
-
-#### Recommendation
-
-* Do not use if you do not need L3 routing.
-* If using tun, make sure FakeIP ranges is included in the tun's routes.
-* Enable `experimental.clash_api.store_fakeip` to persist FakeIP records, or use `dns.rules.rewrite_ttl` to avoid losing records after program restart in DNS cached environments.

-# FakeIP
-
-FakeIP 是指同时劫持 DNS 和连接请求的程序中的一种行为。它通过虚拟结果响应 DNS 请求，在接受连接时恢复映射。
-
-#### 优点
-
-* 在像 L3 路由这样无法进行流量探测的地方检索所请求的域名，以协助路由。
-* 减少对一个域的第一个 TCP 请求的 RTT（这是最常见的原因）。
-
-#### 限制
-
-* 它的机制会破坏依赖于返回正确远程地址的应用程序。
-* 仅支持 A 和 AAAA（IP）请求，这可能会破坏依赖于其他请求的应用程序。
-
-#### 建议
-
-* 如果不需要 L3 路由，请勿使用。
-* 如果使用 tun，请确保 tun 路由中包含 FakeIP 地址范围。
-* 启用 `experimental.clash_api.store_fakeip` 以持久化 FakeIP 记录，或者使用 `dns.rules.rewrite_ttl` 避免程序重启后在 DNS 被缓存的环境中丢失记录。
