Arin changes fees for transfer requests of number resources

Beginning 1 January 2017, ARIN will collect a $300 USD, non-refundable processing fee for each transfer request of Internet number resources, including:

   * 8.2 Merger, Acquisition, and Reorganization transfers; billed to the source (or legal successor) organization.

   * 8.3 Transfers to Specified Recipients within the ARIN region, billed to the source-side organization. The Transfer processing fee is waived when the subject resources are under an existing Registration Services Plan (RSP), and no specific transfer processing fee will be charged to the recipient-side organization.

   * 8.4 Inter-RIR Transfers to Specified Recipients, a fee is billed to the source-side organization if within the ARIN region. This transfer processing fee is waived when the subject resources are under an existing Registration Services Plan (RSP).  No specific transfer processing fee will be charged to recipient-side organizations.

This fee will be invoiced to the source organization’s billing Point of Contact (POC) and are to be paid before request evaluation begins. It will replace the current $500 resource transfer fee on the existing fee schedule. https://www.arin.net/fees/fee_schedule.html

Transferred resources will be subject to annual fees as stipulated by the fee schedule, including registry maintenance fees or corresponding Registration Services Plan. Additional fees may apply based on the status of the source or recipient organization at the time of transfer.

This change arose out of a community consultation, which is available for review at:

https://arin.net/participate/acsp/community_consult/09-01-2016_transferfee.html

If you have additional questions, please contact ARIN Financial Services via Ask ARIN, while logged into your ARIN Online account.

Capacity of Link.

Yesterday I did an article on Cambium and Libre.  I have been asked about AirfFiber.  Here is stats from an AirFiber 24 link.  The link is 1.5 kilometers.

Frequency. Doesnt really change on 24ghz
Temperature. It's winter in Indiana

Libre and Cambium

What Can Libre do for the Cambium operator?

Number of registered SMs. This AP has 7

 

Interface traffic
Number of GPS Satellites tracked
Modulation

Libre can be setup for thresholds.  Any of the above graphs can be set up to alert based upon a threshold.  You could setup an alert that says if SMs on an AP drop by 10% kick out an alert.  This could alert you to possible frequency issues.   You could set a threshold for if traffic reaches a certain level.

Networking foundations

In an article earlier today, I wrote about certifications and the ISP.  The biggest area I see folks go wrong when it comes to networking is having a good understanding of design. One of the analogies I like to use is building a house.   You have several key roles when you build a house.  These can be directly applied to the networking world.

The first is the Architect. Everything starts with this person or team’s vision. The Architect lays out the design and how the network will function. This person needs a wide variety of skills.  They know the product lines they are supporting, they know how these products fit into the overall vision of the network, and they know the limitations of what they are working with, to name just a few of their many skills. These are your CCIE and higher level CCNP folks in certification terms.  They have enough breadth of knowledge to see the entire picture.  Not just what the device in front of them can do. A network architect would know that a certain wireless CPE does not fully support a VPLS tunnel, and would either recommend not using that equipment or come up with a workaround to implement it into the network, if in fact, they were using VPLS.  Many large companies have Architects who implement and validate network designs. These are then pushed to the next group of folks to implement.

The “tradesmen” or “tradeswomen” are the ones who actually implement the designs around the Architects blueprints for the network.  Just like a house who has carpenters, brick layers, and roofers, so do you have folks who know wireless, routing, security, and other disciplines.  These are the folks who can make the machines do what they want them to do. They work off the blueprints to actually make the network talk and function according to the Architects design. these are your CCNA and CCNP level folks. These folks know the equipment configuration in and out.  They are the most responsible for making things work, and knowing how to make it work. The more experienced of these folks typically collaborate with the Architects to provide expert opinions on the latest features of the equipment they are implementing or any limitations of the equipment.

Many folks working in the ISP world wear multiple hats at the same time.   There is nothing whatsoever wrong with this.  You just have to know the limitations of yourself and the things you have to work with. I see multiple illustrations of this on a daily basis. Clients take a router and make it do BGP, OSPF, PPPoE termination, firewall rules, and other things.  Sometimes this is a budgetary thing, maybe just a lack of understanding, or it can even be a sales hype thing. however, not having an understanding of the design and architecture of a network can be costly.

Anyone can build a house. Go to the lumberyard and get some materials, some tools, and watch a few YouTube videos. Bam you are set.  That will probably work until the first time it rains, or it gets cold. Then you are wondering where your design went wrong.  Using plastic on your roof sounded like a good idea until the wind ripped it.  Same can be said in networks.  Start and always have design considerations in mind.  Not just design, but how individual components are best used in that design. Then rely on the tradesmen  to implement them.  You might be one and the same, but don’t wing it as you go.

Learning, certifications and the xISP

One of the most asked questions which comes up in the xISP world is “How do I learn this stuff?”.   Depending on who you ask this could be a lengthy answer or a simple one sentence answer.  Before we answer the question, let’s dive into why the answer is complicated.

In many enterprise environments, there is usually pretty standard deployment of networking hardware.  Typically this is from a certain vendor.  There are many factors involved. in why this is.  The first is total Cost of Ownership (TCO).  It almost always costs less to support one product than to support multiples.  Things like staff training are usually a big factor.  If you are running Cisco it’s cheaper to train and keep updated on just Cisco rather than Cisco and another vendor.

Another factor involved is economies of scale.  Buying all your gear from a certain vendor allows you to leverage buying power. Quantity discounts in other words.  You can commit to buying product over time or all at once.

So, to answer this question in simple terms.  If your network runs Mikrotik, go to a Mikrotik training course.  If you run Ubiquiti go to a Ubiquiti training class.

Now that the simple question has been answered, let’s move on to the complicated, and typically the real world answer and scenario.  Many of our xISP clients have gear from several vendors deployed.  They may have several different kinds of Wireless systems, a switch solution, a router solution, and different pieces in-between.  So where does a person start?

We recommend the following path. You can tweak this a little based on your learning style, skill level, and the gear you want to learn.

1.Start with the Cisco Certified Network Associate (CCNA) certification in Routing and Switching (R&S).  There are a ton of ways to study for this certification.   There are Bootcamps (not a huge fan of these for learning), iPhone and Android Apps (again these are more focused on getting the cert), online, books, and even youtube videos. Through the process of studying for this certification, you will learn many things which will carry over to any vendor.  Things like subnetting, differences between broadcast and collision domains, and even some IPV6 in the newest tracks.  During the course of studying you will learn, and then reinforce that through practice tests and such.  Don’t necessarily focus on the goal of passing the test, focus on the content of the material.  I used to work with a guy who went into every test with the goal of passing at 100%.  This meant he had to know the material. CompTIA is a side path to the Cisco CCNA.  For reasons explained later, COMPTIA Network+ doesn’t necessarily work into my plan, especially when it comes to #3. I would recommend COMPTIA if you have never taken a certification test before.

2.Once you have the CCNA under your belt, take a course in a vendor you will be working the most with.  At the end of this article, I am going to add links to some of the popular vendor certifications and then 3rd party folks who teach classes. One of the advantages of a 3rd party teacher is they are able to apply this to your real world needs. If you are running Mikrotik, take a class in that. Let the certification be a by-product of that class.

3.Once you have completed #1 and #2 under your belt go back to Cisco for their Cisco Certifed Design Associate (CCDA). This is a very crucial step those on a learning path overlook.  Think of your networking knowledge as your end goal is to be able to build a house.  Steps one and two have given you general knowledge, you can now use tools, do some basic configuration.  But you can’t build a house without knowing what is involved in designing foundations,  what materials you need to use, how to compact the soil, etc.  Network design is no different. These are not things you can read in a manual on how to use the tool.  They also are not tool specific.   Some of the things in the Cisco CCDA will be specific to Cisco, but overall it is a general learning track.  Just follow my philosophy in relationship to #1. Focus on the material.

Once you have all of this under your belt look into pulling in pieces of other knowledge. Understanding what is going on is a key to your success.  If you understand what goes on with an IP packet, learning tools like Wireshark will be easier.  As you progress let things grow organically from this point.  Adding equipment in from a Vendor? Update your knowledge or press the new vendor for training options.  Branch out into some other areas ,such as security, to add to your overall understanding.

WISP Based Traning Folks.
These companies and individuals provide WISP based training. Some of it is vendor focused. Some are not.  My advice is to ask questions. See if they are a fit for what your goals are.
