IPv6

statefull avec etat

stateless sans etat

exemple:

2001:0db8:0000:85a3:0000:0000:ac1f:8001 = 2001:db8:0:85a3::ac1f:8001

1/128 est l'adresse localhost, semblable à 127.0.0.1 en IPv4

DNSMASQ

sur openwrt:

https://www.linux.com/topic/networking/advanced-dnsmasq-tips-and-tricks/

dnsmasq.conf

https://sites.google.com/site/virtualdesktoplinkboxbox/home/computing/electronics/routers/openwrt?tmpl=%2Fsystem%2Fapp%2Ftemplates%2Fprint%2F&showPrintDialog=1

server=/raspi/10.25.1.2
server=/zotac/10.25.2.10
server=/nas/10.25.5.5
server=/macbook/10.25.3.7

Go into the /etc/dsnmasq.d/ directory, and add a new config file (you can name it something like 20-custom_records.conf) that will contain your entries:

address=/plex.lan/192.0.2.11
address=/deluge.lan/192.0.2.12   

Pour les paramètres DNS et DHCP, adaptez simplement ce que dd-wrt génère par défaut à chaque instance dnsmasq spécifique au VLAN. Jetez un œil à /tmp/dnsmasq.conf comme modèle pour ces paramètres.

local-ttl=1
expand-hosts
domain=dom
address=/computer.dom/11.22.33.44

https://www.systemajik.com/ubuntu-and-openwrt-dnmasq-setup/?cn-reloaded=1

dnsmasq --test 

will do basic syntax checks on the config files

WIFI

WiFi, both 2ghz and 5ghz at the same time on the same SSID:
