Очень нечетное сетевое значение по умолчанию направляет behavour

Я выполняю сервер 16.04 и недавно сделал dist-обновление после перезагрузки, я не мог получить сетевое соединение.

Когда я проверяю с помощью ping-запросов любой домен:

$ ping google.com
ping: unknown host google.com

$  ping 8.8.8.8
connect: Network is unreachable

$ ping 10.1.1.1
PING 10.1.1.1 (10.1.1.1) 56(84) bytes of data.
64 bytes from 10.1.1.1: icmp_seq=1 ttl=64 time=0.996 ms

проблемы nslookup

 nslookup google.com
;; connection timed out; no servers could be reached

Но если я указываю маршрут по умолчанию:

$ nslookup 
> server 10.1.1.1
Default server: 10.1.1.1
Address: 10.1.1.1#53
> google.com
Server:         10.1.1.1
Address:        10.1.1.1#53

Non-authoritative answer:
Name:   google.com
Address: 172.217.8.174
Name:   google.com
Address: 172.217.8.174
Name:   google.com
Address: 172.217.8.174
