Obfuscating IP Addresses as Hostnames, (Tue, Aug 25th)

Hostnames can be used to mask IP addresses, a technique that can be leveraged in security exploits. For instance, attackers might use hostnames to obscure malicious requests targeting cloud metadata services, such as those vulnerable to Server Side Request Forgery (SSRF). A common defense against such attacks involves blocking or filtering requests containing specific IP addresses like 169.254.169.254.
