This line will replace the last octet of ipv4 adresses in a given file with a zero:

sed -i '' -e 's/(([0-9]{1,3}.){3})[0-9]{1,3}/\10/g'

# The following example shows a way to use iptables for basic round-robin load balancing, by redirecting
# packets two one of three ports based on a statistic counter.
#
# TCP packets for new sessions arriving on port 9000 will rotate between ports 9001, 9002 and 9003, where
# three identical copies of some application are expected to be listening.
#
# Packets that aren't TCP or that related to an already-established connection are left untouched, letting
# the standard iptables connection tracking machinery send it to the appropriate port.
#
# For this to work well, connections need to be relatively short. Ideally there would be an extra layer

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• A Russian translation of this article can be found here, contributed by Timur Demin.
• A Turkish translation can be found here, contributed by agyild.
• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
