GitHUB's Config Files NOTES and spaces

[FoodMaven]

Is there a reason for spaces in the info notes differing from the top three commands and the bottom three about disabling IPv6? Is one set correct and the other incorrect?

It reads:

README.md
Don't forget to disable IPv6 with the commands:

sysctl -w net.ipv6.conf.all.disable_ipv6=1
sysctl -w net.ipv6.conf.default.disable_ipv6=1
sysctl -w net.ipv6.conf.lo.disable_ipv6=1

To disable IPv6 permanently, add to /etc/sysctl.conf:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

	Corrected "Iv6P" typo.

@OP

The first set of commands is applied "on the fly" and will not survive a reboot. The second set of commands alters a boot-time configuration file and is therefore a more stable solution.
