Depletion of IPv4 address space has been the motivating factor for moving to IPv6. Projections show that all five RIRs will run out of IPv4 addresses between 2015 and With an increasing Internet population, a limited IPv4 address space, issues with NAT and an Internet of things, the time has come to begin the transition to IPv6! IPv4 has a theoretical maximum of 4.3 billion addresses, plus private addresses in combination with NAT. IPv6 larger 128-bit address space provides for 340 undecillion addresses. IPv6 fixes the limitations of IPv4 and includes additional enhancements, such as ICMPv6.

Describe the representation of an IPv6 address. Describe types of IPv6 network addresses. Configure global unicast addresses. Describe multicast addresses. Describe the role of ICMP in an IP network (include IPv4 and IPv6).

I’m not a partisan guy. I don’t choose my friends based on party affiliation. I don’t defriend people on Facebook who simply disagree with me on one particular issue. As a result this mentality yields friendships on both sides of the marriage equality issue. Both sides have often heard my many jokes on how everyone should have the same right to be miserable when it comes to the marriage issue. I have also joked [with some seriousness] that some probably fear same-sex couples might be more successful with it when it comes to divorce.
But the bottom line is for heterosexual people – this is not about us. You can still have your personal beliefs. You will not be forced to marry the same sex. Your liberty is unchanged. You only have to share it now just like the air you breathe.
With regards to personal and religious beliefs about marriage: When marriage was an institution governed only by the church, religious sects governed who could and could not marry. This became a civil rights issue the moment that secular governments got involved with the institution and starting licensing the rite and essentially turning it into a legal entity. Judges and Magistrates who perform marriages are performing a civil service much like your local secretary of state signs off on a corporation. They are not religious positions – they are civil positions and this notion of religious infringement conflicts with their duties in government. They should quit if this cannot be reconciled. Bear in mind, however, I do believe Pastors, Rabbis, Imams, etc. have the right to exercise a religious exemption to performing these ceremonies.
Just because I have not been all that great a fan of marriage due to failures on my part with two marriages does not mean I am against marriage. While I discourage all of my friends to get married unless it is an absolute necessity, having that right is inalienable. It was never about wanting to as much as it was about being able to.
I assure you the world will not end. There will be no one setting themselves on fire. There will be no one moving to Canada. There *will* be a lot of awkward conversations between celebrity couples who now must fulfill promises to get married. There will be wedding-related businesses expanding into this new market and there will be a surge in overall marriages – which will mean later on down the road we will see who will be the real winners – Divorce Attorneys. 🙂
But for a lot of good people out there, there will be happiness that comes with this sense of normalcy.
