+# 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
+
+*
+
+#### 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
+
+* Enable `dns.independent_cache` unless you always resolve FakeIP domains remotely.
+* 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
+
+*
+
+#### 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
+
+* 启用 `dns.independent_cache` 除非您始终远程解析 FakeIP 域。
+* 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。
