# Simple IPv6 rotation for avoid YouTube blocking (SLAAC)
|
|
|
|
## Requirements
|
|
- A host with IPv6 support providing a ``/64`` IPv6 prefix. (If your server provider provides smaller prefix lengths such as ``/128`` it is not sufficient for rotation)
|
|
- Docker with IPv6 networking enabled so that invidious can access the internet via IPv6
|
|
|
|
## Setup
|
|
### If the IPv6 address on your host is dynamically configured via Stateless Address Autoconfiguration (SLAAC)
|
|
Add the following to ``/etc/network/interfaces`` or equivalent configuration.
|
|
|
|
Note: The configuration syntax shown assumes use of ifupdown (/etc/network/interfaces). On systems using Netplan, systemd-networkd, or NetworkManager, IPv6 privacy extensions must be enabled via their respective configuration formats.
|
|
|
|
This will enable the IPv6 privacy extensions which will allow the kernel to automatically generate new random IPv6 addresses which are temporary and stay assigned for the specified lifetime.
|
|
```
|
|
iface eth0 inet6 auto
|
|
privext 2
|
|
pre-up echo 2 > /proc/sys/net/ipv6/conf/eth0/use_tempaddr
|
|
pre-up echo 3600 > /proc/sys/net/ipv6/conf/eth0/temp_valid_lft
|
|
pre-up echo 1800 > /proc/sys/net/ipv6/conf/eth0/temp_prefered_lft
|
|
```
|
|
In this case the prefered lifetime is set to 30 minutes and the valid lifetime to 1 hour. Every 30 minutes a new temporary address will be assigned by the kernel.
|
|
The old address will be kept for 30 minutes longer (valid lifetime) for any remaining connections using it.
|
|
|
|
|
|
### If your IPv6 configuration is static
|
|
|
|
Run the below script every 30 minutes via a cronjob as root
|
|
|
|
``/usr/local/bin/ipv6-rotate.sh``
|
|
```
|
|
#!/bin/bash
|
|
# Set your network prefix (first 64 bits)
|
|
PREFIX="2001:db8:1234:5678"
|
|
INTERFACE="eth0"
|
|
|
|
# Generate random interface ID (last 64 bits)
|
|
INTERFACE_ID=$(printf "%04x:%04x:%04x:%04x" $((RANDOM % 65536)) $((RANDOM % 65536)) $((RANDOM % 65536)) $((RANDOM % 65536)))
|
|
|
|
#Enable prefering temporary addresses
|
|
echo 2 > /proc/sys/net/ipv6/conf/"$INTERFACE"/use_tempaddr
|
|
|
|
# Add the IPv6 address
|
|
ip -6 addr add "${PREFIX}":"${INTERFACE_ID}"/64 dev "$INTERFACE" valid_lft 3600 preferred_lft 1860
|
|
```
|
|
Replace the ``PREFIX`` and ``INTERFACE`` variables according to your setup. Note that if your IPv6 address is ``2001:db8:1234:5678::1``, the correct prefix is ``2001:db8:1234:5678``.
|
|
|
|
#### In the crontab:
|
|
```
|
|
*/30 * * * * /usr/local/bin/ipv6-rotate.sh
|
|
```
|
|
Don't forget to make it executable: ``chmod +x /usr/local/bin/ipv6-rotate.sh``
