Windows client support for edns

Hi,
Please can you help me ? I want to know if a windows client (win 10) can be configured to send edns requests when dns requests are attempted to be sent ?

The reason I am asking is that there are many routers that do not support dns/tcp and we need a Srv record with > 512 bytes in it (limit of std dns/udp).

Testing using dig on the client shows that with the +edns flag the larger flag is returned.

Thank you,

Andrew

Hi ,

EDNS is a specification for expanding the size of several parameters of the Domain Name System (DNS) protocol.

Based on my research, EDNS is supported by DNS server instead of windows client.
