UDP/TCP serial module or 18F67J60?

I need to develop a new product that needs to send some packets to up to 6 remote servers and must resolve domains like www.myweb.com by DNS.

All the six sockets must be open at same time and the packets are small, less than 100bytes every 3 seconds so there's no need to high speed device.

I was searching and found some Wiznet chips like W5100 which is a bit old and seems to have not DNS, all is by MAC and IPv4.

W7500 seems to have DNS domain resolution, easy configuration with AT commands but only one socket.

I'm not a network protocol expert, until now I was sending data(IoT) with GSM/GPRS modules with very easy AT commands, so if you know about some SoC or module that works by AT commands please tell me.

The other solution is to use a 18F67J60 but I have no libraries for CCS.
I have no time to develop this, please put me in the right path.
Thanks.

If you can work with serial and modules, then I suggest you go the ESP8266 way with AT commands. Cheap, WIFI and does everything you need way too easily.

The other option is like the chip you suggested. However, you may have quite a struggle porting the tiny TCP/IP implementations available for the Arduinos. Time to market will be quite uphill unless you know what you're doing.
