### Problem Description

I have an ios application which uses mDNS to find specific devices on the network then it resolves an IP address so then the application can connect to it through websocket. It has been working for years now. Recently I updated my iPads to iOS 17 and suddenly this functionality stopped working.
APP uses **_http._tcp.** to obtain the IP of ESP8266
Then I used [mDNS_Web_Server.ino](https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266mDNS/examples/mDNS_Web_Server/mDNS_Web_Server.ino) from the library file to test, I can resolve the IP normally in IOS16 (tested using discovery&ABC-bonjour APP) and Android devices, but cannot resolve it normally in IOS17.
In IOS17 I can access http://esp8266.local through the browser and it returns the device's IP.
When I thought it might be a problem with the APP, I tried Arduino-ESP32
I used [ESP32-mDNS_Web_Server.ino](https://github.com/espressif/arduino-esp32/tree/master/libraries/ESPmDNS/examples/mDNS_Web_Server) in the ESP32 library file and found that under IOS17, the APP can resolve the ESP32 IP normally.Both apps discovery&ABC-bonjour can resolve to the IP of ESP32 through MDNS normally.
May I ask what content is missing in the MDNS library of ESP8266 that causes this problem?
