 #### Recommendation
 
-* Do not use if you do not need L3 routing.
+* 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.

 * 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。
