172.16.0.1

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 172.16.0.1 can be represented (actually there are more formats, since you can mix multiple formats).

Name	Private-Use Networks	A descriptive name for the special-purpose address block.
RFC	RFC1918	The RFC through which the special-purpose address block was requested.
Allocation Date	February 1996	The date upon which the special-purpose address block was allocated.
Source	Yes	172.16.0.1 is valid source address of an IP datagram that transits two devices.
Destination	Yes	172.16.0.1 is valid destination address of an IP datagram that transits two devices.
Forwardable	Yes	A router may forward an IP datagram to 172.16.0.1 between external interfaces.
Globally Reachable	No	An IP datagram to 172.16.0.1 is not forwardable beyond a specified administrative domain.
Reserved-by-Protocol	No	The special-purpose address block is not reserved by IP, itself.

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 172.16.0.1 through several backlists and find out who considers this IP to be malicious. Click DNSBL Lookup to get real-time data.

If the IP 172.16.0.1 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 172.16.0.1 </RequireAll>
iptables	iptables -A INPUT -s 172.16.0.1 -j DROP
Nginx	location / {   deny 172.16.0.1; }
Node.js	if (request.connection.remoteAddress === '172.16.0.1') {   return console.log(403); }
PHP	if (filter_input(INPUT_SERVER, 'REMOTE_ADDR') == '172.16.0.1') {   return print(403); }
Python	if (os.environ['REMOTE_ADDR'] == '172.16.0.1')   return print(403);
web.config	<security>   <ipSecurity allowUnlisted="true">     <add ipAddress="172.16.0.1"/>   </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 172.16.0.1.
