ipv6

ipv6 notes

simple basics:

  • The Internet uses IPv4 addresses to find computers and devices
  • Growing number of servers and computers and devices
  • Running out of IPv4 addresses, so
  • Need to slowly switch over to IPv6 system.

linux / digitalocean
to show ipv6 interfaces
ip -6 addr show eth0

testing commands:
sudo netstat -tulpna | grep nginx
should have tcp and tcp6

nginx
to refresh settings
sudo nginx -s reload

sudo nano /etc/nginx/sites-available/default
to add in
listen 80;
listen [::]:80;

nginx -V
should have –with-ipv6

sudo nano /usr/local/nginx/conf/nginx.conf

My devices now are assigned 1x IPv4 address, and 2x IPv6 address each. Why?
