country’s telecommunications network.
Governments that have complete control over their country’s network may also install
an “internet kill-switch”. The UN has condemned the use of such single shut-off
mechanisms.
Border Gateway Protocol (BGP) Manipulation
BGP is the protocol that manages the global routing system of the internet, which
allows packets of data to travel from their source to their destination. It works via
requiring every network node (known as an Autonomous System or AS) making up the
global internet to constantly advertise which IP addresses it gives access to.
These announcements flash back and forth across the whole network, marking the
route between any two points on that network, each of which is a cluster of IP
addresses. This protocol is what makes it possible to access a website or app hosted in
another location.
By manipulating the contents of these announcements, or BGP routing tables, an ISP
can make the Internet Protocol (IP) addresses of any number of its customers
“disappear” from the internet, effectively cutting off access for those people. This is
more precise than a full network shutdown and allows for exceptions to be made, such
as for government officials.
IP Address Blocking
Websites and apps rely on web servers to host their content, each of which has its own
IP address. This unique numerical address allows devices to find and communicate
with each other.
ISPs can create lists of IP addresses that correspond with services they want to block
