80 Domain Name Local Router New

It is important to note that the server name indication is an extension of the tls protocol.
Domain name local router. Run your own dns server and tell your router to use it as the default resolver for your network. Get a public domain name. Reason for asking is that i am tinkering with some home automation nas and a pi hole ad blocker.
Dnsmasq was used as the dns resolver but because dnsmasq was also the dhcp server it would integrate the 2 very nicely. Now if we check show cdp neighbors on r2 we see that r1 has a domain name appended to it. A domain is usually run by a domain server its not something intended for small local networks.
Always default the router can use smtp to transfer mail to any domino server in the local domino domain that runs the smtp listener. The server itself may only be accessible inside your network but the dns will be available anywhere. If you set as dhcp normally will the router as your dns server hostnames like that should work.
I am using the rax200 as my dhcp on my local network and the router modem supplied by my isp just as my modem. My previous router was a good old simple wrt54g running openwrt. Hence only tls routers will be able to specify a domain name with that rule.
The local domain name is used for the router to provide normal dns service. You can give your own network a name and have all your machines on it that is easy depending on the os your using. If anyone has any thoughts or advice it would be apprecaited.
How can i find out my local domain name or set one within the router config. Router config ip domain name name example. This command allows you to set a domain name for the router.
