Where is the content of my generated resolv.conf coming from?

  • 772

I have a Ubuntu 14.10 server with resolvconf installed.

In /etc/resolvconf/resolv.conf.d/base, I have:

nameserver 127.0.0.1

In /etc/resolvconf/resolv.conf.d/head, I have:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

In /etc/resolvconf/resolv.conf.d/original, I have:

domain members.linode.com
search members.linode.com
nameserver 207.192.69.4
nameserver 207.192.69.5
nameserver 97.107.133.4
options rotate

My /etc/resolvconf/resolv.conf.d/tail is symlinked to /etc/resolvconf/resolv.conf.d/original.

Why is my resolv.conf generated like this?

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 74.207.242.5
nameserver 74.207.241.5
nameserver 127.0.0.1
search members.linode.com
domain members.linode.com
search members.linode.com
nameserver 207.192.69.4
nameserver 207.192.69.5
nameserver 97.107.133.4
options rotate

Where are the first 2 and fourth lines from? From my understanding, resolvconf should only use information from head, base, and `tail.

This is my /etc/network/interfaces:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp
resolvconf
