# W5500 SO_REUSEADDR

## Question

Asked by WGR7 on 2020-12-26 in Ethernet Chips.

Hi,

I have a source code that needs setup a socket with reuseaddr option, but the setsocketoption function on the library has not this option. Do w5500 sockets support this option? Is it integrated on chip tcp stack?

There is no reuseaddr option in the w5500. W5500 has a total of 8 sockets, and each socket must be managed by the user.
