193.203.0.0 Geolocation Lookup and Detailed Q&A

193.203.0.0 is an IP address, it represents a device on the Internet.

IP address is used to identify the device that sends or receives data in cyberspace and is represented by a string of numbers.

The number can be displayed in binary, decimal, hexadecimal, etc., as shown in the figure below, with decimal being the most common.

Notice:

A correct IP address has 4 numbers and connected by dot, such as there only 3 numbers in 193.203.0, and 5 numbers in 193.203.0.0.1, they are not correct IP addresses;

The size of the 4 decimal numbers ranges from 0 to 255. If any number exceeds this range, such as 193.203.0.256, it is not a correct IP address.

Sometimes, dot will be replaced by space or hyphen, e.g. 193-203-0-0，193 203 0 0, but generally it is represented by dot, e.g. 193.203.0.0;

If you want to learn more about IP address, please check: What is IP address?

193.203.0.0 is an external address, which is a public IP address on the Internet, and its corresponding device can be accessed by other devices on the Internet.

IP addresses can be classified as public address, private address, and reserved address.

• Public IP address: The overwhelming majority of IP addresses are public addresses and need to apply for registration with the international Internet administrative agency.
• Private IP address: Three IP address segments are reserved in the IPv4 address protocol as private addresses for internal use by the organization.
• Reserved IP address: There are also some reserved addresses, which are used as private IP address space or for special purposes such as internal LAN.

From the screenshot above, you can see the different locations and utilizations of public IP address and private IP address.

Notice:

• The IP address of a device may change, and the device corresponding to an IP address may also change, they are not fixed;
• If you do not want your device uses a public IP address, you can place the device on a private network instead, and use address mapping to achieve access and enhance security.
• Because of the scarcity of IPv4 address, home networking devices usually use private IP and connect to public IP on the Internet through a router.

What are public IP addresses, private IP addresses and reserved IP addresses?

In short, 193.203.0.0 is located in Austria.

Specifically, public IP addresses are coordinated by IANA(The Internet Assigned Numbers Authority）, who first allocates the different IP addresses to five RIRs(Regional Internet Registries).

• ARIN(American Registry for Internet Numbers): including Canada, USA, and some Caribbean Islands
• APNIC(Asia Pacific Network Information Centre): including Asia/Pacific Region
• RIPE NCC(Réseaux IP Européens Network Coordination Centre): including Europe, the Middle East, and Central Asia
• LACNIC(Latin America and Caribbean Network Information Centre): including Latin America and some Caribbean Islands
• AFRINIC(African Network Information Centre): including Africa Region

Organizations in need of IP addresses apply to these allocation centers who coordinate the allocation.

These organizations that get assigned IP addresses then assign these IPs to their corresponding devices, which are basically placed in the country where the applicant organization is located, and we can get the organizations and countries corresponding to these IPs through the Whois information of the IP addresses.

Notice: Sometimes, however, organizations that obtained the IP address may also assign these IPs to other countries, such as multinational telecommunications companies, overseas military bases and other special circumstances.

Although we have used a variety of data sources and technical means other than Whois information of IP address, we still cannot guarantee that the query result is 100% correct. Therefore, the country/region information we provided to which the IP address belongs is correct at 99.99% or more, and in rare cases errors may occur.

How are global IP addresses assigned?

Let's give a simple answer first: IP 193.203.0.0 is located in Vienna, Vienna, Austria.

• City longitude: 16.368419647217 °
• City latitude: 48.202629089355 °

Please note above data is only the longitude and latitude of Vienna, Vienna, Austria, not the accurate geographic location of IP user or device.

In some detail, we obtain the city-level positioning of an IP address by comparing data from multiple sources and technical means.

Notice: Regarding the accuracy of this data, because of IP address allocation and variability and other factors, the highest standard city-level IP location accuracy rate in the industry can hardly reach more than 80%, and some websites or businesses claim that their accuracy rate reaches 95% or more are not highly credible.

Of course, the overall IP address location accuracy is difficult to reach more than 80% doesn’t mean that the positioning accuracy of 193.203.0.0 is also 80%. Users can compare and verify data from multiple websites, as well as make network speed tests or take other ways to improve the accuracy rate.

What is the principle of IP address geolocation?

Still, let's give a simple answer first: it is generally not possible to find out the exact location of a user by IP address.

In the last question, we mentioned the accuracy rate of 193.203.0.0 located in Vienna, Vienna, Austria cannot be 100% correct, and it is even more difficult to get the precise location of the next level area, street, and room number.

For example, an IP is assigned to a dial-up ADSL operator, when one of its users dials up, the IP address is occupied. But after the user goes offline, this IP address may be assigned to another dial-up user, and the user will be assigned another IP address after dialing up again to access the Internet. So you can only make sure that this IP is used within this city, but it cannot be sure of a smaller area, street, or a room.

However, the Internet service provider (ISP) has log records of the usage of an IP address, and if necessary (e.g., at the request of police), the ISP can provide more accurate user information and geographic location of an IP address at a certain time.

Of course, such precise information of an IP address is generally not disclosed to the public for the purpose of protecting users' privacy.

The location of your public IP address 193.203.0.0 is shown in the map as follows, country/region: Austria, region: Vienna, city: Vienna. Longitude (16.368419647217 °) and latitude (48.202629089355 °) is the geographical information of the city, not the exact location of the user. This website cannot guarantee 100% correct, we only provide reference information.

This topic is rather specialized, so let's first know about what is reverse DNS lookup for IP addresses.

DNS is the acronym for Domain Name System. The domain name system establishes links between domain names and the IP addresses, and a DNS server is specialized for the work. The forward DNS lookup is according a domain name to look up IP address, and the reverse DNS lookup is according an IP address to look up the corresponding domain name.

In Linux system, you can use “host 193.203.0.0” instruction to make reverse DNS lookup.

• If 193.203.0.0 has no setup of reverse DNS, it will return Null or 193.203.0.0 itself, for example: the reverse DNS lookup of 52.173.80.234 returns 52.173.80.234.
• If an IP address has setup of reverse DNS, it will get a different result from this IP, for example: the reverse DNS lookup of 66.249.64.145 returns crawl-66-249-64-145.googlebot.com.

Notice: Reverse DNS lookup needs to be carried out online. Occasionally, there will be timeout and other errors in the case of network congestion, which will make the IP that has setup of reverse DNS does not return correctly but the original IP. In this case, it is necessary to do a few more “host 193.203.0.0” instructions or try again at another time.

What is reverse DNS of an IP address?

By querying databases, we can know whether 193.203.0.0 is a proxy IP and what type of proxy it is.

193.203.0.0 is not a proxy IP Address.

When someone uses a device to access another device online, usually it is the source IP accesses the target IP directly, but in some special cases, for example, the source IP is restricted by the firewall and cannot access the target IP directly, or the visitor wants to hide its real IP address, an intermediate IP can be used as a transit, and it is called proxy IP.

Notice: Whether an IP address is a proxy IP generally does not change in the short term, but it may still change in the long term.

The Whois lookup tool is designed to allow people to find the responsible agency and administrator when there is network problem. At present, Whois tools are widely used in the network technical level, for example, if Telecom Internet service providers find there is network problem, they can quickly notify the relevant responsible person to diagnose and deal with it. In addition, if there is network resources abuse, such as a lot of spam from a certain IP address, they can also contact the person in charge of spam complaints to deal with it.
