My Dyn setup is documented below. ...

Introduction While creating CAA records, I found myself needing a new DNS provider. During that process, I thought it would be a good idea to document what it take to host a website and how the internet works (in a very limited sense). To host a website on the public internet, you need three things: domain name DNS record(s) web host Typically, most domain registrars offer basic DNS support. In addition, most web hosts also offer basic DNS support. However, you can (and probably should) have these three services hosted at three separate companies (you don’t want all your eggs in one basket). ...

Introduction Certification Authority Authorization (CAA) is a new DNS record specifying which Certificate Authorities (CAs) are allowed to issue certificates for a domain. Introduced by RFC 6844, CAA protects websites by only allowing certificates to be issued by specific CAs. If an attacker were to take over a website, they would only be able to obtain a certificate from a CA specified in DNS CAA records, limiting the damage they could do. While CAA records aren’t going to completely stop certificate misuse, they are easy to implement and are part of a larger security plan. ...

Introduction Recently, I’ve been thinking more and more about backups for my small (but growing) homelab. The golden rule is to follow the 3-2-1 method for backups: 3 backups 2 different types of media 1 backup offsite Current setup Currently, I keep an encrypted external HDD at home and another at work. Every couple weeks, I perform a backup to both and rotate the drives (this covers a 2-1-1 backup). ...

However, after the 2016 Dyn DDoS, I’ve decided to add a second dynamic DNS service provider, in case Dyn goes down again. ...

Introduction With the winter weather, we’ve been having brownouts and power losses more frequently. I wanted to purchase a UPS to protect my equipment from this, but I also wanted to receive alerts when the power goes out, and possibly shutdown equipment. For this, I need an Uninterruptible Power Supply (UPS) and a computer to monitor it with. Hardware As you guessed by now, I’m going to be using my Raspberry Pi to monitor the UPS. I’m using the Raspberry Pi because it is a low power device, it is always on (hosting a webserver, Unifi controller, and a few other things), and can be run off the UPS it is monitoring. ...

My main issue is that the DHCP server does not integrate with the DNS server. Because of this, DHCP names/leases are not automatically added to DNS.
