77.204.203.137

IP format

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