Customer Frequently Asked Questions

Below we have tried to answer or address some common concerns with our customers that we have encountered over the years.

A: We recommend using the speed test provided by Check your speed here with this Speed Test. *This test works well for speeds up to 100Mb. If your circuit is over 100Mb, is does not yet make a highly accurate measurement.

A: Many Internet Service Providers (or ISPs) will sell you, what they call a high bandwidth circuit. For example, ISP XYZ might be selling a 100Mb connection for cheap, only to find out, that the 100Mb is only for Download speed, and the Upload Speed is only 1Mb. These types of Connections are known as Non-Symmetrical (or Asymmetrical) connections / circuits. LeaseNet will only sell fully 100% Symmetrical connections and data circuits. A 100Mb connection from us, will be 100Mb for Download AND Upload.

A: Many Internet Service Providers (or ISPs) will sell you a shared circuit, such that from your premises to theirs it is shared with many other clients. The result being that your speed will vary at different times of the day, depending on how many others are sharing. Many cable companies sell circuits this way, due to the nature of their installed network. LeaseNet never sells shared circuits.

A: Many Internet Service Providers (or ISPs) will sell you an over subscribed circuit. For example you purchase a 100Mb circuit, and the phone company will connect the building you are in, or the whole block with a 100Mb connection, and then sell more 100Mb connections to other businesses in the building/block. If the total pipe from the building is only 100Mb then how could more than one user have a "real" 100Mb connection? The answer is, they do not. This becomes another type of shared circuit. LeaseNet never sells obversubscribed circuits.

A: We use Layer2 Technologies to connect our customers where possible. This provides a direct Ethernet to Ethernet type of connection from the customer premises to us. No routing between us and the customer, just speed-of-light connection from you to our core equipment. Compare this with carriers offering MPLS (packet switched) type of connections. MPLS /Packet is of course cheaper for them to operate but each single packet of data could take a completely different path through the network and then predicting quality of service and speed becomes nearly impossible. LeaseNet only offers direct Layer2 connections to its customers. It is an elevated premium circuit that guarantees level of service and speed between the customer and us. I like to think of this like a dedicated railroad from you to us, that only your trains can use. Other carriers typically supply the cheaper MPLS / Packet networks, and this looks more like a mesh network of many roads with many cars fighting for a place to drive.

Where this technology really shines is with multi-location businesses. We can connect your very different physical locations via our Layer2 Technologies, and make them appear to all be on the same physical network. Let's think about that for a minute. I could have an office in Houston and an office in Dallas connected via our Layer 2 connections that could share printers and other resources as if they are in the same office. They could even use the same single Domain Controller if it is a Microsoft environment. They could share one central Firewall, and so on. The list of advantages and possible single shared resources goes on and on.

A: We encourage you to use a DNS server (Domain Name Server) that is local to your network. We see a lot of customers using Google Domain Name Servers (Which of course are not local at all). We understand this is an easy way to get going, but it does not provide good performance down the road. When you request a web page in your browser (such as Firefox or Edge) each graphic, and video, etc is a resource that has to be looked up on a DNS server first. If your DNS is slow, then it does not matter how fast your connection(s) are to the internet, everything will appear to be slow. So, our advice: If you are a bigger environment that has the resources, consider running your own local DNS server. Else, our customers are very welcome to use our DNS Servers.

A: NNI = Network to Network Interface and/or ENNI = Ethernet Network to Network Interface. These both refer to the type of connections we have with our carriers that help us to provide Layer 2 technologies to our customers.

A: The current Internet Protocol addressing system used by all devices on the internet is known as IPv4. It has been around since the birth of the internet as we know it and is implemented by every device connected to the world wide web / internet. The reality has come, that those addresses are becoming less and less available, and we will soon run out. To solve this problem, IPv6 has been introduced and is now being slowly adopted to alleviate the addressing issues of the internet.

IPv4 uses a 32 bit addressing scheme. For example.

IPv6 uses a 128 bit addressing scheme, For example. 0000:0000:0000:ABCD:EF01:2345:0000:0000.

Thus providing the equivalent of 655368^8 addresses, which is 340,282,366,920,938,463,463,374,607,431,768,211,456 or about 340 undecillon.
It has been suggested this is enough addresses for every grain of sand on the planet earth, and then some.
