Fatpipe.org IP Packet Header Drawings

Matt Baxter created very descriptive IP packet header drawings in 2008. Unfortunately, his website, which was where he posted them, has been inaccessible for a long time. I was able to recover these copies of the original PDF files up using the Internet Archive’s Wayback Machine I uploaded the PDF versions of the drawings here in case anyone else is interested in scalable, high quality copies of them.
