Features:
- Full Spectrum: Imitate the solar spectrum, customize a more ideal full life cycle full spectrum supplementary light program, covering the entire visible spectrum of 400nm-780nm; CRI 90+, infinitely close to natural light, suitable for every cycle of plant growth, effectively promotes plant growth, and improves crop yield and quality.
- High PPFD: The PPFD of every 32W grow light bulb is 380.34μmol/s/㎡@1FT: and the beam angle is 120 degrees, which provides a wider coverage area, ensuring that your plants receive sufficient light from all angles. Gives plants more supplementary light, allowing them to radiate vitality and thrive.
- Upgraded Bracket: We have reinforced and upgraded the bracket, extended the fixed base to make the bracket more stable. with a height adjustment range from 35 to 65 inches, whether it's a potted plant or a tall plant, you can easily position the light according to your plant's needs.
- Patented COC Technology: Chip on Ceramic, SANSI's patented technology replaces the traditional Mcpcb aluminum substrate with a non-conductive ceramic heat sink, and directly solders the LED chip on the ceramic heat sink, effectively reducing the system thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, makes the SANSI bulb has higher light efficiency.
- Safe & Reliable: The lamp body is made of special ceramic material, and the flame retardant grade reaches V0; the reinforced insulation structure design, no risk of electric shock, is safer; the whole shell material reaches the WF2 anti-corrosion grade, which is more reliable; low IR, less heat radiation, avoiding close Distance exposure burns plants.

Overall it was an OK book. I am already ...
Format: Paperback
Overall it was an OK book. I am already "competent" with DNS, specifically the BIND9 implementation but I got the book as reference material since the official documentation is a little sparse. The fifth edition (not sure about the others) even covers, albeit a little too briefly, how to deal with reverse lookup zones with subnet masks that do not fall on octet boundaries.

Thicker than I anticiapted
Format: Paperback
The encyclopedia of DNS books, meaning thicker than a phone book.
I like the fact that this book is thick but so easy to read and follow along with. If you know nothing about DNS, this book makes it easy to learn about DNS. It starts with the history of DNS and then explains the hierarchy of the DNS tree. A must read if you want to improve your understanding of the internet and what happens under the hood for name resolution.

Best practical book on DNS and how it works
Format: Kindle
I was interested in finding out more about how DNS is deployed and operated in practice. The first few chapters in this book deliver very well in this regard. My motivation was to find out more about how a certain type of Internet attack -- the "open DNS resolver attack" -- works. Even though this book was written well before this attack became popular and well known -- and therefore the attack is not mentioned, let alone analyzed -- the book was still quite helpful to me.
