I have been working on making the web sites more mobile friendly.  Let me know if I missed a page. 

ipv6 ready

After further testing on one of the Apache2 Web Servers it fully resolves IPv6.

Fortinet is checking into a way for the other web server to work IPv6.  You can setup an IPv4 VIP from URL to IP.   They are checking on doing it with IPv6.

I have decided to create an entire blog page dedicated to IPv6. This site is on a server that is configured for IPv6.  After a year of working on IPv6 with Fortinet from AT&T.   I finally abandoned AT&T and switched to Comcast. 

I followed Thorsten’s site


Comcast brought me down all 8 interfaces and both WIFI interfaces the Prefix-Delegated Subnets for IPv6.  I made the other changes to the firewall and IPv6 has /64 addresses on every interface and can route in and out.  

EUI-64 addressing for devices

IPV6 Address is


AAAA:BBBB:CCCC:DDDD is the the first 64-bit of the 128-bit and never changes from your ISP. EEEE:FFFF:GGGG:HHHH is the 64-bit for your internal network or the /64

Your devices MAC address is what creates the automatic EUI-64 address. Here is my old AT&T /64 block address: 2600:1702:980:25e0. Here is the MAC address of a NIC:   00-D8-61-F4-A9-23. You take your MAC and spit it in half and add FF:FE to the middle  00DB:61FF:FEF4:A923. Your computer will create a IPv6 address:   2600:1702:980:25e0:00DB:61FF:FEF4:A923


You just joined Comcast and they gave you a shiny new /61 block.  What to do?

Your WAN side will have your public NA address.  They will give you PD address and tell you /60 or /61. 
/60 = 16 x /64 blocks. 
/61 = 8 x /64 blocks

Your prefix delegate might be 2600:1702:980:25e0?

2600:1702:980:25e0:  The last zero is what will increment.  /61 block means you have 0 to 7.

On my Fortinet 60E I have it setup to auto-increment each interface.   Check out the notes in that section
