1.1.1.1

IPv4 addresses can be represented in several formats. This may be useful to store IP addresses in a more efficient way (for example, storing IPs as UNSIGNED INT requires less space and may be a faster solution) or to bypass some filters (for example, something doesn’t allow you to specify IPs from private range, but since it filters only quad-dotted IPv4 address representation you can specify IP as decimal number). Below are listed almost all formats as IP 1.1.1.1 can be represented (actually there are more formats, since you can mix multiple formats).

Dozens of companies are managing lists of blocked IP addresses in order to stop spamming, unethical hacking, and other malicious actions. These blacklists (also known as DNSBL and RBL) can contain both IP addresses and domains. Below we will try to lookup IP 1.1.1.1 through several backlists and find out who considers this IP to be malicious. Click DNSBL Lookup to get real-time data.

If the IP 1.1.1.1 has aggressive behavior or should not have access to your private resources, you can block/ban it using your firewall, webserver, or programming language. Below are some examples of how to restrict this IP address from accessing your machine.

Algorithm	Example
Apache	<RequireAll>   Require all granted   Require not ip 1.1.1.1 </RequireAll>
iptables	iptables -A INPUT -s 1.1.1.1 -j DROP
Nginx	location / {   deny 1.1.1.1; }
Node.js	if (request.connection.remoteAddress === '1.1.1.1') {   return console.log(403); }
PHP	if (filter_input(INPUT_SERVER, 'REMOTE_ADDR') == '1.1.1.1') {   return print(403); }
Python	if (os.environ['REMOTE_ADDR'] == '1.1.1.1')   return print(403);
web.config	<security>   <ipSecurity allowUnlisted="true">     <add ipAddress="1.1.1.1"/>   </ipSecurity> </security>

Hashing algorithms are one-way functions that do not have a reversible algorithm. Most commonly they are used to check data integrity, prevent the data forgery, and hide sensitive information. For example, some developers may hash the clients IP addresses, that is why below are listed hashes of different hashing algorithms for IP 1.1.1.1.
