The computer is not lost in the computer, and the horse is really horses, I really want to smash him. Have you encountered this situation? In the case of this type of Truma, it is lurking in your computer, and the opportunity to threaten or destroy your system. ConnecWatch, Back Orification Spy, BodeTect, The Cleaner, etc. is a software designed for such bugs. As long as someone attacked your computer, it will be protected, and the record is even counterattack. Of course, there are many kinds of intrusion, such as Netbus, Netspynew, ICQT, Back Orific Remote, Port Scan. The webmaster didn't have time to test, and I didn't guarantee absolute protection. But this is not the theme of this article. What you have to say is what you know when you know the invasive IP address, if you find an intruder location? "For example, 140.119.4) or Domain Name (such as www.chati.com)?
-------------------------------------------------- ------------------------------ About IP Address and DNS Please refer to the network addressing mode and internet service introduction these two Article Network Address Management Status IP Address must be registered with Internet (www.internic.net), while Domain Name is registered to the local network management center. There are three levels of online management centers on the Internet (NET in net): 1. The international level international level is only in Internet, and the NIC and Intercontinent NICs around the world are managed. 2. Intercontinental INTERNIC does not directly manage the entire Internet, and the net resources underout are partitioned (Europe, Asia ...). For example, Taiwan, Japan, Hong Kong and other Asia Pacific countries, managed by Asia-Pacific NIC, APNIC, at www.apnic.net, is not directly managed by INTERNIC. 3. National grade Domain Name does not hang in the national code (such as: http://www.allfile.com) is not by interNic management is managed by Intercontinental NIC, but there is a national code from NIC management, conventions It is the two national code plus NIC is the name of the country (www. ** nic.net). For example, the country code of Taiwan is TW, then the Taiwan Network Management Center is Twnic (www.twnic.net). Supplement: At present, Taiwan's WHOIS system has been suspended, so if you want to check, you must call us.
But the United States is an exception, because INTERNIC is located in the United States, so the United States's Domain Name is midually in the art of Internic. There is a special exception to hang. MIL's US military network information is managed by nic.ddn.mil (US military defense network), not by Internet management.
-------------------------------------------------- ------------------------------
Three situations named Domain Name
Although it is also domain name, you may have different situations of three naming. In many countries * .edu. * Is managed by units other than NICs (such as the Ministry of Education), and attributes are not necessarily three letters, and there is no attribute. Readers should pay more attention when judge the character of the unit, so as not to find information. 1. Standard country code three yards property code (or no country code, only the property code) is commonly used in Europe, American countries, and some Southeast Asian countries. Such as Taiwan is common * .edu.tw, * .com.tw, *. Org.tw, US * .com, * .edu. 2. Standard country code 2 yord code. Take the most recent Japan, the People's Republic of China as an example. The company's property is CO, the community property is OR, and the COM defined by the three code, and ORG is slightly different. If the HOMEPAGE of Japan is www.bandai.co.jp, if the reader wants to use the company name to patch up the full host name, you should pay attention to the area where Japan is only the two yards, otherwise it is www.bandai. Com.jp will have an error (Note: In the international communication example, whether it is radio communication, the international Yueyang phone, and even internet access, Taiwan is divided into two different countries). 3. There is only a standard national code and there is no attribute code. For example, the host of Australia is only * .au host name, no other COM, CO or any unit attribute code is directly connected to the unit name. By Domain Name, Isolated Connection Unit Information on the Internet, the usage of the WHOIS service is queried by the WHOIS service, and WHOIS should be used to check someone's phone or other information (it is a bit like finger or now very The popular tracing service is like Whowhere, Bigfoot, AOL, but the NIC is used to identify the telephone and address, technical contact, etc. of the connection unit. Unit data that meets the NIC administrative privilege will be stored in the Whois host of the unit, the convention is the WHOIS NIC name NET. For example, the Asia-Pacific Network Management Center Whois Server is Whois.Apnic.net, the Taiwan Network Center WHOIS Server is Whois.Twnic.net. When you know the Domain Name of a host, you can find information such as the address of the connection unit in the following order. WHOIS query system use overview
When you get a Domain Name or IP Address, use the appropriate WHOIS system (WHOIS. ** NIC.NET) according to the previous step, the syntax is as follows: WHOIS-H
Do you understand the above parameters? The webmaster explains you with a relatively simple method.
HP.com is because of its invalidation (Tw.jp), so it is not from Intercontinental NIC, then let's go to InterNic. So in the browser's URL Touch http://whois.internic.net/, in the blank column of its query type hp.com If you still don't understand, 唉 ... give up is also a part of life .. .. taught
-------------------------------------------------- ------------------------------
Example demonstration
First, look at the country code first. No country code, ask WHOIS.ISTERNIC.NET; there is a national code, to WHOIS. Country code nic.net (ex. Whois.twnic.net). Also, if you want to check the contact details of the US military unit (if you find someone to use the US Navy to invade your computer), you need to query the NIC.ddn.mil to find the information. For example, Isolated the US Army's information: But the FBI and other investigative institutions are government units, non-military units, and pay attention to inquiries.
★ Domain Name
Data from Domain Name You can find an IP Address FQDN from NSlookup, you can directly find the intruder network directly to local NIC: 1. An example of the US invasion by the USA by the host by XXX.AOL.com The name is found to have no national code, so directly to the Iis.internic.Net. From this, we can find information on the technical person in charge of American Online and telephone, fax, etc., you will prepare your system documentation, send a fax to the Ocean! 2. An example of the Bay in the Bay has a TW country code from Hope Net Intrusion (CDED1. Hope.com.tw), so to the local NIC query. However, because the WHOIS database did not know how to do it, please change from http://dbms.seed.net.tw/ The name of Hope.com.tw, and then play 104 checkpoints asked the company. phone!
Now if you are inquiry directly by Whois.Twnic.net: ★ Only IP Address check
If you find that you are invaded by 168.95.109.222, assuming that you don't know this is a Hinet's network, and this IP address is not Domain Name, you must first grade the IP Address level and then query the INTERNIC. (IP grading description, please press here) (hereinafter, as the sample site is font, if there is a similar, purely a coincidence). 1. An example of 15.4.75.2 This IP address is 15 starts, for a Class A network, so to Internic Query 15.0
Isors this IP Address is all of HP, and the IP Address is the Class B network by 140.111.32.53. This IP address is the Class B network, and you need to query twice. First, INTERNIC inquiry 140.111.0 is found out for the Ministry of Education of the Republic of China. Quroom 140.111.32.0 in the WHOIS. Twnic.net is unfortunately, because the TWNIC material library is invisible, you can't know which academic unit is this. Waiter, make a call to twnic asking! It is possible for the Experience of Website to be a Sun Yat-sen University. 3. An example of 203.66.35.1 This is a Class C IP, so you must query at least twice, usually three times. The order is international -> Intercontinental -> State.
