255.255.255.255 Reserved IP Address
255.255.255.255 is a reserved IP address reserved by the IP address management agency and not assigned as a public or private IP. The reserved IP is generally used for special purposes, such as software, private networks, hosts, subnets, documents, conversions, multicast, broadcast, local communication, loopback, relay, link, mapping, testing and future usage. Non-professional users are rarely involved.

255.255.255.255 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.Description of IP Address in Binary, Decimal and Hexadecimal Description of IP Address Class A/B/C/D/E and Network ID, Host ID
A correct IP address has 4 numbers and connected by dot, such as there only 3 numbers in 255.255.255, and 5 numbers in 255.255.255.255.1, 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 255.255.255.256, it is not a correct IP address.
Sometimes, dot will be replaced by space or hyphen, e.g. 255-255-255-255，255 255 255 255, but generally it is represented by dot, e.g. 255.255.255.255;

255.255.255.255 is a reserved IP address, not a public IP address, and cannot be directly accessed on the Internet.
In addition to allocating public IP addresses, the IP address allocation agency has reserved some IP addresses for special usage. These reserved IP addresses are listed in the table below.
IPv4 reserved addresses:

The reserved addresses for IPv6 are not listed here, please see: Reserved IP addresses - Wikipedia.
255.255.255.255 generally cannot be used as a private IP address of a router.
IP addresses can be classified as private IP addresses, public IP addresses and reserved IP addresses.
- Public IP addresses: The overwhelming majority of IP addresses are public addresses and need to apply for registration with the international Internet administrative agency.
- Private IP addresses: 3 IP address segments are reserved in the IPv4 address protocol as private addresses for internal use by the organization.
- Reserved IP Addresses: 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.
From the definition of IANA, the private IP address is also classified as a reserved IP address. There are mainly 3 IP segments:
|Class||Address range||Number of addresses||Number of networks|
|Class A||10.0.0.0 ~ 10.255.255.255||16777216||1 Class A|
|Class B||172.16.0.0 ~ 172.31.255.255||1048576||16 Class C|
|Class C||192.168.0.0 ~ 192.168.255.255||65536||256 Class C|
Our website judges that the above 3 IP segments are classified as private IP addresses. The IP addresses of these 3 IP segments can be used for routers, and other special IP addresses are classified as reserved IP addresses. Therefore, 255.255.255.255 is not the private IP address used by the router.
Note: If 255.255.255.255 is forcibly used as the router IP address, it may cause IP conflicts and other situations that makes the router cannot be used normally.
The IP address 255.255.255.255 belongs to the 255.255.255.255/32 IP segment in CIDR format. The starting IP and ending IP are 255.255.255.255. This IP address segment has a total of 1 IP addresses, the scope is Subnet, Reserved for the "limited broadcast" destination address.
Short answer: No. The IP address geographic location of 255.255.255.255 cannot be found.
Three types of IP addresses correspond to:
- Public IP address: Used on the Internet, you can find out where the IP address belongs to, generally accurate to the city level.
- Private IP address: Used in the internal network, there is no corresponding geographic location, and the IP address geolocation cannot be found.
- Reserved IP address: Used for special purpose, there is no corresponding geographic location too, and the IP address geolocation cannot be found.
You can use Whois lookup to find out the administrative agency of an IP address, and even the phone number and other contact information of the administrator.
Using the Whois tool to look up 255.255.255.255 will yield a lot of information, and we pull out the main information as follows:
- Administrative agency: SPECIAL-IPV4-FUTURE-USE-IANA-RESERVED
- Description：Addresses starting with 240 or a higher number have not been allocated and should not be used, apart from 255.255.255.255, which is used for "limited broadcast" on a local network. This block was reserved by the IETF, the organization that develops Internet protocols, in the Standard document and in RFC 1112. The documents can be found at: http://datatracker.ietf.org/doc/rfc1112
- Address: 12025 Waterfront Drive Suite 300 Los Angeles CA 90292 United States
- Administrator：Internet Assigned Numbers Authority
- Tel: +1-310-823-9358
- E-mail: email@example.com
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.
