CTF

Highlighting RFC-3936 Uniform Resource Identifier (URI) (section Rare IP Address Formats)

These additional IP address formats are not allowed in the URI syntax due to differences between platform implementations. However, they can become a security concern if an application attempts to filter access to resources based on the IP address in string literal format. If this filtering is performed, literals should be converted to numeric form and filtered based on the numeric value, and not on a prefix or suffix of the string form
