# ngrok forwarding

## Question

Asked by EdiWiz on 2024-03-16 in Ethernet Chips.

It is possible to connect to tcp://0.tcp.ap.ngrok.io:19914 using W5500? If it is not possible, what other similar alternative can I use?

It is not possible to directly enter the DNS address in the driver.

Use the function below in ioLibrary_Driver/Internet/DNS/dns.h to obtain the IP address and then enter the IP address.
ex)
DNS_run(dns_ip, site, site_ip);
connect(sn, site _ip, port);

Please refer to the link below

> 안녕하세요 driver상에서 dns주소를 직접 입력할 수 없게 되어있습니다. ioLibrary_Driver/Internet/DNS/dns.h에서 아래 함수를 사용하시어 ip주소를 얻은후에 ip주소를 넣어주시면 됩니다. ex) DNS_run(dns_ip, site, site_ip); connect(sn, site _ip, port); [\[image\]](https://maker.wiznet.io/forum_uploads/wiznet/original/2X/3/3351a7c0bccad92b4c120daa01084e83370652a8.png)

I answered by mistake in the other thread, but I’ll check it out and also try it.

Thanks.
