Yet another case for IPv6 for service providers

So recently I have been posting about the Cambium Networks QOE box I have been testing. After having this run for about a week I figured I would share this tidbit about usage. 55.39% of my traffic is IPV6 traffic. Most of this would be streaming traffic to various folks like NetFlix and Amazon and gaming traffic. My household consists of three people. No kids. Implement IPV6 now if you are a service provider and thank me later. https://blog.j2sw.com/networking/wisps-ipv6-is-the-answer-to-some-of-your-issues/ #packetsdownrange

Preseem now supports IPv6

https://docs.preseem.com/changes Features IPv6 Preseem now supports IPv6 for all use cases. This includes the ability to assign subscribers a prefix of arbitrary length. IPv4 with Prefixes of Arbitrary Length Previously Preseem modelled subnet assignments to customers as a number of /32 assignments. For example a subscriber who was assigned a /30 would result in four internal /32 mappings. Preseem now supports assigning any prefix length to a subscriber without expanding these into /32 entries internally.

WISPs: IPv6 is the answer to some of your issues

Many Wireless Internet Service Providers (WISPs), especially newer startups, struggle with nat issues and having enough public Ip addresses to go around. Invariably, you start running into double nat issues pretty quickly. Then you get the dreaded gamer call: Many times they don’t know why they are even calling. They just know the magic box is saying this is bad. This is related to how many layers of nat between your edge and them. Many times you are natting at the edge, then...

ARIN resources and the Service Provider

Internet Service Providers (ISPs) can be intimidated by all of the facets of working with the American Registry of Internet Numbers (ARIN). I have put together a guide that outlines common things you, as a service provider, need to do. This guide is not an end-all how-to. Throughout, I am posting videos and links taken from the ARIN site to help. This article is more of an outline of what a service provider needs to do. The majority of the steps below will...
