# Trying to learn DHCP client

## Question

Asked by 480VAC on 2020-09-11 in Ethernet Chips.

I’m trying to learn how to create the DHCP client on the 5100S. I found in another post a very intriguing looking link - but it is broken:

<https://www.wiznet.co.kr:8011/UpLoad_Files/ReferenceFiles/W5100_Appnote_DHCP.zip>

Is there a new link to this? I tried [wiznet.io](http://wiznet.io), but that did not work.

Thank you!

Hello,

I think you can refer file on this page (scroll down till bottom, there you will see Appnote zip file).

There it was… Thank You. It may also be in the W5100S-EVB software folder too,
