OK. I've got IPv6. Now, what do I do with it?
Posted on 2015-01-31
My ISP just upgraded us to IPv6. I see that I have a /56 network. Sounds wonderful. What can I do with it?
The first thing I wanted to do was create an Apache website that uses SSL on one of my shiney new IPv6 addresses (I have a block of 18 ipv4 addresses, and they are all in use, so, going ipv6 is a great thing for this).
But, I don't know how to do it?
What are the steps here? For example, this is what I would do with ipv4 addresses...
1. Use ipcalc to calculate out the address space:
michael@backup01:/home/michael# ipcalc 192.168.1.10/28
Address: 192.168.1.10 11000000.10101000.00000001.0000 1010
Netmask: 255.255.255.240 = 28 11111111.11111111.11111111.1111 0000
Wildcard: 0.0.0.15 00000000.00000000.00000000.0000 1111
Network: 192.168.1.0/28 11000000.10101000.00000001.0000 0000
HostMin: 192.168.1.1 11000000.10101000.00000001.0000 0001
HostMax: 192.168.1.14 11000000.10101000.00000001.0000 1110
Broadcast: 192.168.1.15 11000000.10101000.00000001.0000 1111
Hosts/Net: 14 Class C, Private Internet
This shows me that I have 14 usable addresses. I know my HostMax is the gateway, and I know my HostMin is the device (router). So, I have 13 usable in this example.
2. Consult my spreadsheet to see that 192.168.1.1 - 192.168.1.8 are all in use.
3. Configure my new site on 192.168.1.9.
What does this procedure look like with IPv6?
