# W6100 cannot resolved DNS with CNAME

## Question

Asked by design4 on 2021-07-19 in Ethernet Chips.

Hi genius.

Im using W6100 with HTTP client example code given.

Currently I cannot resolve the DNS ip for CNAME. But DNS ip for A-Record can.

Below is the code:-

```
DNS_run(SOCK_DNS,dns_server, (uint8_t *)Domain_name, Domain_IP,AS_IPV4);
```

When success, it will released Domain_IP.

Thanks in advanced.
