"Efficiently Managing LAN with Traditional DNS and DHCP Methods"

This article provides a guide on setting up bind and dhcpd to create a functional dynamic DNS setup for a LAN, ensuring DHCP clients self-register with DNS and enabling working forward and reverse DNS lookups. The author, a homelab sysadmin, emphasizes the importance of reliable DNS in a networking environment and shares their experience in maintaining a linked bind and dhcpd setup for over a decade. The article also hints at a future project involving the creation of a local ACME-enabled certificate authority for issuing LAN certificates.

"ICANN Proposes .INTERNAL Domain for Private Home Networks"

ICANN has proposed creating a new top-level domain, .INTERNAL, intended for internal use only, to address the uncoordinated and potentially harmful use of ad hoc TLDs for private purposes. After a consultation process, .INTERNAL was chosen over .PRIVATE as the preferred TLD. While ICANN's board still needs to approve the creation of .INTERNAL, some organizations already use ad hoc TLDs for internal purposes, and ICANN advises understanding the potential costs of using private namespaces.

Prolific Puma: Uncovering a Massive Cybercrime URL Shortening Service

Security researchers have uncovered a massive cybercrime operation involving a link shortening service provided by an actor known as Prolific Puma. Prolific Puma has registered thousands of domains, primarily on the US top-level domain, to facilitate the delivery of phishing, scams, and malware. The researchers observed that the short links led to various landing pages, including phishing and scam sites. The operation is believed to involve multiple actors, and evidence suggests that text messages are the main channel for distributing the malicious links. Prolific Puma has registered up to 75,000 unique domain names since April 2022, with the majority of domains created on the usTLD. The actor uses private registration protection for some of the domains, which is not permitted in the .US namespace. The researchers have provided indicators of Prolific Puma activity, including hosting IP addresses, domains, and email addresses found in domain registration data.

"Maximizing DNS Security: Top Servers and Strategies"
