# Resolve internet address and connect to that webserver

## Question

Asked by gossamer on 2016-10-13 in Ethernet Chips.

How do I resolve the address for example: [www.google.com](http://www.google.com) from w5100 and convert it to IP to which I can make TCP connection ?
Is that even possible when socket accept only destination IP address.

Thanks

I guess this would be my answer: [ietf.org/rfc/rfc1035.txt](https://www.ietf.org/rfc/rfc1035.txt)
I need to implement DNS client to send request to DNS port 53 with name of server and get response as an IP address… ![:frowning:](https://emoji.discourse-cdn.com/twitter/frowning.png?v=12)
I kinda hopped it would be implemented on uC level ![:wink:](https://emoji.discourse-cdn.com/twitter/wink.png?v=12)

You go here [url][http://www.wiznet.co.kr/product-item/w5100/\[/url\]](http://www.wiznet.co.kr/product-item/w5100/%5B/url%5D), scroll down the page, and download archive with application notes how to implement DHCP, DNS and other stuff.

Thanks Eugeny. Thats more or less digestible version of RFC ![:slight_smile:](https://emoji.discourse-cdn.com/twitter/slight_smile.png?v=12) just the important part, package definition
