What is carrier grade NAT and what is it used for?
We are configuring routers with IPv4 addresses and would like to configure IPv6 address instead of IPv4 for some devices. Please suggest me the best way of doing it and things to be considered (IP validations & subnet Mask, etc) while doing this enhancement.
How do you subnet in IPv6? I know most subnets are all /64′s, but I need to be able to assign larger blocks to labs to they can then, in turn subnet their blocks. I keep looking at the bits and the hex, but I am not quite getting how to define and organize the [...]
We wonder where we could a most exhaustive list of hosts, hardware, and appliactions compatible with IPv6. For example, we know that Linux OS and a kernel with a version older than 2.4 are compatible with IPv6 (if activated). Windows Vista and Seven are also compatible with IPv6. Our aim is to establish a group [...]
I hear a lot about IPv4 and IPv6, but what happened to IPv1, IPv2, IPv3, and IPv5?
What are the top technical issues most enterprises run into during IPv6 migration?
Are there any disadvantages in changing IPv4 into IPv6 IP addresses?
Is it possible to outsource your IPv6 transition?
I know how to calculate IP addresses under IPv4. How do I calculate addresses in IPv6?
How can a small to medium-sized organization (SMB) with limited resources prepare for the transition to IPv6? What’s our best bet to transition to IPv6 cheaply?
Hi, Can you recommend a few good websites or books to get started with IPv6? Thanks.
I’m talking to my current ISP about IPv6 migration, and I’d like to know whether service providers typically charge you to run dual-stack or not. Should I expect Internet service providers to charge extra for any other IPv6 migration costs?
I’m looking to migrate my IPv4-based network to IPv6. But I keep hearing that IP addresses work their way into parts of a network infrastructure that we don’t normally think of. So before I do a trial-and-error approach to testing the IPv6 network, what are there common places IP addresses hide so that I can have [...]
Hi, My company has public-facing IP addresses, so with the pending IPv4 address exhaustion, I know an IPv6 migration is inevitable. If my goal is to migrate all of the wide area network’s IPv4 addresses to v6, what are some very basic steps I need to take to put together a migration plan, i.e., speak [...]
What sources would you recommend for training on IPv6. I’m not really interested in a router/firewall configuration course. I want training/education on the IPv6 protocol and addressing schema. I know I can go read lots of RFC’s on it but that is rather dry and can be difficult to absorb. Do you know any good [...]
Can I buy an IPv6 address? How does the purchasing process work? I heard that ARIN will give enterprises IPv6 addresses for free, but is this true and what are the conditions?
If IPv4 addresses are running out in the next year, why aren’t more people using IPv6 more often?
Can an IPv6 address be spoofed?
What do Internet2 and IPv6 have in common? Does Internet2 have anything to do with IPv6?
What is the number of IPv6 addresses left? How many IPv6 addresses are there, and when will they run out?
