======How to add dns servers to Gentoo Linux behind a DHCP server======
(and probably other Linuces, too)

Open ##/etc/resolv.conf## with your editor of choice (emacs, vi, nano...).

It should read like:
%%(/etc/resolv.conf)
# Generated by dhcpcd from <interface>
# /etc/resolv.conf.head can replace this line
domain <local domain>
nameserver <ip address>
# /etc/resolv.conf.tail can replace this line
%%

close the editor. The server will take its domain and dns server from a dhcp server. DNS servers will be asked from top to bottom. It is resolv.conf.head we want. Control the resolv.conf before writing one, however; there you find instructions on where to add static content (hopefully).

Look up [[http://www.opennicproject.org/nearest-servers/ | your nearest openNIC servers]] or put in static ones.

#%emacs /etc/resolv.conf.head#%

(or the file resolv.conf pointed you to with your editor of choice)

%%(/etc/resolv.conf.head)
nameserver 87.98.242.252
nameserver 46.105.212.15
nameserver 108.61.210.58
nameserver 62.113.200.106
rotate
%%
(or the nearest nameserver from you)

If you have static IP, take a look at [[http://forums.gentoo.org/viewtopic-p-7085734.html | http://forums.gentoo.org/viewtopic-p-7085734.html]].
debian resolvconf is explained here: [[http://www.opennicproject.org/configure-your-dns/how-to-configure-a-pppoe-internet-connection-on-a-debian-box/ | http://www.opennicproject.org/configure-your-dns/how-to-configure-a-pppoe-internet-connection-on-a-debian-box/]]

Now restart your interface (or remove the network cable and put it back in, or switch wlan off and on):
#%/etc/init.d/net.<interface> restart#%

If you are using systemd, my condolences, and use the appropriate tools.

After the interface is back up, check:
#%gview /etc/resolv.conf#%

Your /etc/resolv.conf.head now should be inserted into /etc/resolv.conf

Now is the time for a check of the OpenNIC tlds. Follow this link. If it works, you are successful: [[http://grep.geek/ | http://grep.geek/]]
