Outdated link?

Hi. Trying to understand openwrt dns, i found this:

Right way to change the DNS

If you have IPv6 you'll need to disable peerdns in the wan6 section as well so that the DNS advertised by the ISP is not added to the list. With one instance of dnsmasq there is only one list of default external DNS servers. They are used equally in a round-robin / failover fashion. It doesn't matter where you put a list dns but it makes the most sense to put them in a wan interface configuration block.

which led here:

@frollic

For the clients, option 6 from https://openwrt.org/docs/guide-user/base-system/dhcp_configuration#dhcp_options.

and then to follow this link which seems to be down:
http://www.networksorcery.com/enp/protocol/bootp/options.htm

so i guess this is an fyi but also, is there another place to read what would be at that link?

btw i see this but its not helping me make a connection with option 6 mentioned above.

and then to follow this link which seems to be down:
http://www.networksorcery.com/enp/protocol/bootp/options.htm

It only explains the params, and what they do - https://web.archive.org/web/20220401023959/http://www.networksorcery.com/enp/protocol/bootp/options.htm

You could use https://www.iana.org/assignments/bootp-dhcp-parameters/bootp-dhcp-parameters.xhtml instead.

frollic, thanks for your response. is it correct to say you are referencing the dhcp protocol option 6 from rfc2132?

Yes, correct.
