"dns.nextdns.io" a large number of connection errors
Hey, I am using nextdns cli 1.11.0 under centos8
Recently, it was discovered that a large number of "i/o timeout" appeared in the log, and there was a problem with the local area network DNS resolution.
First of all, I suspect that there may be a problem with the network, so the normal "dns.nextdns.io" IP can be resolved through other DNS service providers "8.8.8.8" nslookup.
as follows:
[root@NextDNS ~]# nslookup dns.nextdns.io
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
dns.nextdns.io canonical name = steering.nextdns.io.
Name: steering.nextdns.io
Address: 37.252.249.233
Name: steering.nextdns.io
Address: 84.17.37.186
Name: steering.nextdns.io
Address: 2a00:11c0:17:429::3
Name: steering.nextdns.io
Address: 2a0b:4341:509:186:5054:ff:fe0e:98d3
I ping the resolved IP, and the results are as follows:
[root@NextDNS ~]# ping 37.252.249.233
