Public NAT64/DNS64 (Workaround for Git Updates on IPv6 Only Nodes)

Why should I care?

Will enable full use of GitHub on IPv6 limited nodes by using a public NAT64/DNS64 resolver

Description

Command

1

Update /etc/resolv.conf to use 1.1.1.1 and the public NAT64/DNS64 resolver

Read more about 1.1.1.1

WARNING - This will overwrite any existing DNS entries, make sure you want to do this!

echo \
"#Public DNS Servers
nameserver 1.1.1.1
nameserver 1.0.0.1
nameserver 2606:4700:4700::1111
nameserver 2606:4700:4700::1001
#TREX Public DNS64 Resolvers
nameserver 2001:67c:2b0::4
nameserver 2001:67c:2b0::6" | sudo tee /etc/resolv.conf

2

Use chattr to prevent any VPS cloud configs from resetting /etc/resolv.conf

This will make /etc/resolv.conf immutable

sudo chattr +i /etc/resolv.conf

Only run this if you need to edit /etc/resolv.conf again, you must disable immutability

sudo chattr -i /etc/resolv.conf

Check your node's DNS connection settings
