Google Public DNS Servers Hijacked on 16th March 2014

Google Public DNS Servers i.e., 8.8.8.8 (which are running in Anycast mode)  was hijacked on 16th of March 2014 for the Internet users of Venezuela and Brazil for nearly 22 mins. Google's Public DNS servers are used for "130 billion DNS queries on average (peaking at 150 billion) from more than 70 million unique IP addresses each day." This makes Google most popular Public DNS service in the Internet world. It is suspected that Hackers exploited a well-know vulnerability in Border Gateway Protocol. There is no-way in BGP to check if particular IP address segment belongs to a particular ISP. RPKI and BGPSEC are the solution of this flaw but these two protocols are still in initial phase and lot or works needs to be done on these protocols. In this particular case, attack kept users from using the internet but no malicious activity has been traced till yet. No redirection of DNS traffic to rogue servers has been traced. This lead to suspect that someone might

Public DNS Servers

Domain Name Service (or Server or System) is an internet service that translate easily memorized domain names into IP numbers and vice-versa. DNS Servers can be better understands as Yellow page directory to the Internet. Every ISP runs DNS services for their customers and users. A user can also runs DNS service for its own. There are many DNS servers which are open for all, commonly known as Public DNS Servers. IP addresses of main Public DNS Servers are :- Google Public DNS Servers 1.   8.8.8.8 2.   8.8.4.4 3.   2001:4860:4860::8888 4.   2001:4860:4860::8844 Level 3 Public DNS Servers 5.     4.2.2.1 6.     4.2.2.2 7.     4.2.2.3 8.     4.2.2.4 9.     4.2.2.5 10.   4.2.2.6 OpenDNS Public DNS Servers 11.     208.67.222.222 12.      208.67.222.222 13.      2620:0:ccc::2 14.      2620:0:ccd::2 Norton Public DNS Servers 15.   198.153.192.1 16.   198.153.194.1 Comodo Secure Public DNS Server 17.   8.26.56.26 18.   8.20.247.20 Other Public DNS Server 19.

Why we have IPv6 after IPv4..... Where is IPv5 ?

IP or Internet Protocol, is the primary network protocol used on the Internet, introduced by Vint Cerf and Bob Kahn in 1974. IP version 0 to 3 was introduced and used between 1974 and 1979. After changes and refinements in initial IP protocol, version 4 was introduced in 1981, commonly known as IPv4, described in RFC 791 , which become the backbone of Whole Internet in no time. (IPv4 is know as v4 because it is the fourth version of IP not because it has 4 octets, which is a common myth). TCP/IP Protocol was designed as a part of project ARPANET, whose aim was to interconnect various universities and research institutes of USA. But with the dot com boom, TCP/IP grows like anything and its become a victim of its own success. In Early 90's, expert realized that we will exhaust the whole IPv4 number very soon and there is a need for a new protocol, which should be enough in size to serve the internet community for at least 30-40 years. This lead to new version of Internet Protoco
