An update on policy changes that are no longer under discussion, because they have been adopted by the ARIN Board and implemented by ARIN staff. While these policies will not be discussed at ARIN XXIX, they are important to understand for two reasons. First, they have altered the ARIN Number Resource Policy Manual (NRPM) which may affect your next interaction with ARIN. Second, they provide some background and history on the current policy debates. You may be able to glean a sense of where the ARIN community’s focus is (or at least has most recently been) by understanding the policy changes which have made it through to adoption following the previous PPM.

As a member of the ARIN Advisory Council (AC), I have to stay up to date on all of the goings on in the world of ARIN policy development (that’s kind of the point of the AC). These policy changes affect many people but are fairly hard to keep track of for most (most engineers [...]

As an active member of the ARIN community and an elected member of the ARIN Advisory Council (AC), I am always excited to see new policies implemented (yes, I’m a special breed [...]

Before we look at what breaks, I should probably make sure that you know what it is that I’m talking about here. If you already know all about traditional NAT and address overloading, skip to the NAT444 section. If you are familiar with that as well, feel free to skip right to the list of [...]

Not overly surprisingly, APNIC officially received two more IPv4 /8 (“slash eights”) from the IANA today: Hi, The IANA IPv4 registry has been updated to reflect the allocation of two IPv4 /8 blocks to APNIC in January 2011: 39/8 and 106/8. 39/8   APNIC   2011-01 whois.apnic.net ALLOCATED 106/8   APNIC   2011-01 whois.apnic.net ALLOCATED [...]

I was planning on writing this great breakthrough piece on IPv6 subnet sizes, like how many /48s are in a /32 or how many /56s are in a /24, etc… But then I stumbled across a great PDF from ARIN and realized that all the work was already done. So I ended up not posting [...]
