With contempo news that the government in Russia has signed the "Russian Internet Law", information technology is setting in motion plans to utilise an alternative Domain Proper name System (DNS). This news, alongside Islamic republic of iran'southward contempo test of a state-wide firewall, is some of the latest proof it would appear more and more countries are seeking to take control of their Net infrastructure.
In Russia's case, it appears that some structural changes to its Internet have been in the works for a while. In 2012 the Russian government began blocking spider web users in the land from accessing certain websites based on a set criteria. Subsequently in 2015, a police was passed requiring all software-as-a-service (SaaS) providers to maintain a local copy of all data of Russian citizens. However, to date few have complied with this request with picayune to no repercussion as of yet.
2017 marked further developments when Russian officials issued a ban on all software and websites related to Internet filtering, including virtual private networks (VPNs) and anonymisers, besides as all websites containing instructions on how to access websites blocked by the government.

- Red china wants to ban VPNs to strengthen its 'Great Firewall'
- Russia will block nine VPN providers imminently
This latest "sovereign Internet constabulary" seems to be an attempt past the Russian government to test the feasibility of isolating Russia from the rest of the Cyberspace. This recalls one very similar, successful, system - The Great Firewall of China.
How China's Great Firewall works
China serves every bit the largest example of attempting to control the Internet within its borders, and a big part of its success, in this attempt, is the fact that it started from the very first, edifice architecture for this from scratch.
The Great Firewall was built in 1999, and is the blanket term for the collection of techniques used to filter web traffic in Red china. Two things have made the Firewall possible: Communist china introduced the policy in a much earlier phase of the Internet, allowing the ecosystem to evolve alongside the Cyberspace organically; secondly, state-run monopolies command telecommunications inside China, and these take fully complied with the censorship demanded past the authorities. What has resulted is the largest filtering infrastructure of Internet traffic in the globe, with few, if whatsoever, choke points in and out of the country.
Internet traffic in China tin exist analysed and manipulated by Chinese government far more hands than in a country like the US, for one thing because all Cyberspace service providers in Red china are licensed and controlled by the Ministry building of Manufacture and Information technology. Furthermore, a small-scale number of fiber-optic cables enable virtually all of Red china's Net traffic, these enter the country at ane of ten unlike courage admission points, 7 of which were only added in January 2015. This all leads to almost total control over the Internet.
China then is a unique instance of Internet disconnection. For a country like Russia, where the Internet has been allowed to evolve in a much more integrated way, these roots are now firmly intertwined, significant it will be very difficult to split from them.
Then how realistic is global "splintering" of the Cyberspace?
While the Net is of grade mostly open today, at that place are already restrictions in several countries. For example, Saudi Arabia already restricts DNS, forcing the DNS request traffic through nationally controlled proxy service, with the aforementioned technology is used in China.
Such examples show that there is a clear impulse to secure more control of the Internet along national lines, whilst all the same allowing traffic to flow. Initiatives similar GDPR and other privacy laws can also be seen every bit examples of this. A Us company wanting to do business organization in the Eu, for example, needs to keep all information at that place.
How could a country "disconnect"?
When it comes to Internet censorship, often the outset step (and the easiest) is IP blocking, which has the added bonus of being generally very low cost and piece of cake to deploy. IP blocking works when a country has a "blacklist" of undesirable IP addresses, routers then drop all packets destined to blocked IPs, potentially including the address of what a land would classify as a "sensitive" site, or of a DNS resolver. In Red china, an IP blacklist is injected via Border Gateway Protocol (BGP) using null routing.
The fact that with IP blocking the government tin can maintain a centralised blacklist without much interest from the ISPs, and thus without much risk of leakage, makes it a especially lightweight solution.
Often used in conjunction with IP blocking are DNS-related techniques. Changing a domain name is not nearly equally trivial as changing an IP accost. Routers can disrupt unwanted communication by hijacking DNS requests containing banned keywords and injecting forged DNS replies and DNS tampering falsifies the response returned past the DNS server. Used together, DNS tactics and IP blocking can effectively seal off censored sites and servers on both the domain and IP levels.
In that location are a host of other approaches to imposing command on a country's Net including:
Cocky-censorship: In Red china, ISPs are expected to monitor and filter content on their networks co-ordinate to country guidelines and all Internet companies operating in Communist china are also required by police to self-censor their content. If companies tin't successfully censor their content, they face penalties: warnings, fines, temporary shutdowns and possible revocation of their business licenses. These processes take fostered a culture of cocky-censorship in the country.
Manual enforcement: The Chinese Cyberspace police force has an estimated 50,000 employees. They manually monitor online content, directly deleting content or ordering websites, content hosts and service providers to delete material.
Keyword filtering: Chinese authorities inspect content passing through their pathways, including URLs for blacklisted keywords. However filtering is inconsistent, functioning equally more of a "panopticon" than a firewall.
Is this the dawn of the "splinternet"?
Overall most countries globally withal go on their Internet fully open - and even the near severe systems like Prc are not 100% constructive at complete isolation. While there is certainly a trend of fragmentation which volition probable continue, at nowadays Russia and China are more astringent examples of trying to control the flow of traffic, requests and services.
As such, it looks like anything approaching a "splinternet" is withal a long way off.
