Mi /etc/resolv.conf se ve así:
# 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 127.0.1.1
# OpenDNS Fallback (configured by Linux Mint in /etc/resolvconf/resolv.conf.d/tail).
nameserver 208.67.222.222
nameserver 208.67.220.220
Cuando uso nslookup, parece que uso 127.0.1.1:
moose@pc08 ~ $ nslookup www.google.com
Server: 127.0.1.1
Address: 127.0.1.1#53
Non-authoritative answer:
Name: www.google.com
Address: 173.194.44.17
Name: www.google.com
Address: 173.194.44.16
Name: www.google.com
Address: 173.194.44.19
Name: www.google.com
Address: 173.194.44.18
Name: www.google.com
Address: 173.194.44.20
Pero cuando hago clic derecho en el administrador de red y hago clic en "información de conexión" obtengo:
whois 217.0.43.129
revela que esto pertenece a Deutsche Telekom AG, mi ISP.
¿Por qué el administrador de red muestra esta información? ¿Qué servidor DNS estoy usando actualmente?
dnsmasq
Sí, parece que ejecuto dnsmasq:
moose@pc08 ~ $ ps aux | grep dnsmasq
nobody 1479 0.0 0.0 5468 1404 ?
