Every device that uses the internet for communication must have a network address. A public IP address is needed for establishing connections with other networks, websites, servers, and systems.
The address 103.133.214.234 is an IPv4 address. Its format follows the four numerical sections divided by dots that identify IPv4 addresses.
Someone who is looking up this address may wish to discover the network owner, explain mysterious traffic, troubleshoot a connection issue, or confirm if this is a hosting server. A person cannot identify an individual by their IP address. The reason for this is that a user can be anyone on the network. It is important to look at the big picture when it comes to analyzing traffic and addresses.
How IPv4 Addresses Work in Internet Communication
An IPv4 address has 32 bits, allowing internet systems to recognize an IP destination. The addresses can be both public and private. The former allows communication across the internet, and the latter is used for private networks. Internet service providers, hosting companies, and corporations have access to public addresses because they are highly specialized in the IT field. One server can be located in a data center, shared between users, have a dedicated IP, or be located elsewhere. This is a difference between a DCHP address and a dedicated one, and an essential detail for someone investigating an unknown address.
Checking Network Registration and Ownership
Network registration records can become a valuable source of information about an unfamiliar IP address because they store data about the addresses’ owners.
Regional Internet Registries can provide valuable information about an IP address. They have the authority to register new addresses and make changes to existing data. By reviewing the address 103.133.214.234 and its registration records, it is possible to locate the network’s owner who may have access to the IP address, or at least the technical support department. The address itself may not be associated with any server.
Why an IP Address May Appear in Server Logs
There are several reasons why a webmaster might see an unfamiliar IP address in their server logs. It can appear there when someone views the website, a crawler accesses the page, or a remote request is sent to the server. A careful webmaster will look at the details of these requests and check if anything suspicious is happening. If there is a remote attempt to hack the system, there should be an appropriate response in the server log. A user should consider the following details:
-
Whether unusual requests were denied
-
What time the requests were made
-
What specific documents were asked for
-
What user agents were used
-
If there were failed authentication attempts
-
If the server was hacked or not
-
If the requests were made in a short span of time
A remote user will look at a website’s pages and materials. Unless they are related to hacking or attacking the server, these requests should not be a matter of concern. Some of the traffic may be generated by search engine robots, and some of them might be checking if the site is online.
IP Geolocation Is Not an Exact Physical Address
Various IP geolocation tools can identify what city, region, or country sent the request. The tools are not always accurate, and the region or a country may only represent the company’s area that leased the server. The location of a hosting company’s servers may not coincide with the company’s official location. A user’s IP address can also belong to a company, a VPN, or a proxy server. Therefore, an IP address should not be used to identify someone’s precise residence.
Practical Questions About IPv4 Investigation
Can an IP address be used to identify a user?
An IP address can hardly be used for identifying a specific person. A dynamic address can be assigned to different users, and it is necessary to have specific tools for reviewing a person’s online activity. A user should also have the legal right to do so.
Does an unfamiliar IP address mean that a website is under attack?
An unknown IP address should not be a cause of panic for website owners and administrators. A user should analyze the situation and take into account that traffic requests can come from regular visitors, crawlers, and other servers. There should be no attacks without appropriate data in the server logs.
Can the organization that owns the IP address change?
It is possible for the owner of an IP address to change over time. It is necessary to review the registration records to understand whether there are any recent amendments that would affect the current research. In general, an IP address should be subject to analysis of network records and traffic, and not just rely on one tool or method.
