        "value": "When looking at malicious traffic, one of the things we are interested in are the hosts involved in a particular attack. For example, we check the hostnames or IP addresses that were serving up malicious code.\r\n\r\nBefore getting further, let\u00e2\u20ac\u2122s define a few concepts to better understand the topic we are discussing today. A host name can be:\r\n\r\nA domain name (i.e. http://example.com/)\r\nA fully qualified domain name (i.e. http://test.example.com/)\r\nAn IP address (i.e. http://127.0.0.1/)\r\nIt\u00e2\u20ac\u2122s not as usual, but IP addresses can indeed be directly used as the URL and when that happens it is called an IP-Literal Hostname (see Eric Lawrence\u00e2\u20ac\u2122s post on this subject).\r\n\r\nIP addresses (IPv4) follow the dot-decimal notation which is four numbers, each ranging from 0 to 255, separated by dots. But then, to make things a little more complicated, we have exceptions, such as the non-dotted IP literals, in decimal (http://2130706433/) or octal form (http://017700000001/).\r\n\r\nThis takes us to a recent infection chain for the RIG exploit kit where we came across such an occurrence.",
