Transport Fee's (Taxes and random telecom fee's)
by A. Pishdadi 15 Sep '12

15 Sep '12

Hello Everyone, We purchase 10Gig waves for transport out of our datacenter and are trying to figure out why the taxes on the circuits are so much. We are paying around 60% additional in taxes and fee's on top of the cost of the circuit. Ofcourse when we were negotiating pricing , it seemed like a great price until we got our first bill, they forgot to mention that we would be paying such fees. It seems like these taxes would be for companies who would be using transport services for voice, but we are all data. Is there any way to get a tax exempt status? How come the same fee's do not apply to dark fiber? We are in process of getting dark fiber to replace the transport circuits but its going to take quite some time as we have a few more years on some of the contracts. The dark fiber we do have there is no taxes at all. Can anyone shed any light on this?

Layer2 over Layer3
by Philip Lavine 14 Sep '12

14 Sep '12

To all, I am trying to extend a layer2 connection over Layer 3 so I can have redundant Layer connectivity between my HQ and colo site. The reason I need this is so I can give the "appeareance" that there is one gateway and that both data centers can share the same Layer3 subnet (which I am announcing via BGP to 2 different vendors). I have 2 ASR's. Will EoMPLS work or is there another option? Philip

RIPE NCC now allocating IPv4 address space from the last /8 netblock

http://arstechnica.com/information-technology/2012/09/europe-officially-run… Europe officially runs out of IPv4 addresses RIPE NCC now allocating IPv4 address space from the last /8 netblock by Iljitsch van Beijnum - Sep 14, 2012 3:20 pm UTC Earlier today, the RIPE NCC (Réseaux IP Européens Network Coordination Centre) announced it is down to its last "/8" worth of IPv4 addresses. This means that it is no longer possible to obtain new IPv4 addresses in Europe, the former USSR, or the Middle East, with one small exception: every network operator that is a "RIPE member" or "local Internet registry" (LIR) can obtain one final block of 1024 IPv4 addresses. To fulfill these requests, the RIPE NCC is keeping that last /8, which contains 16.8 million addresses, in reserve. RIPE NCC None of this comes as a surprise given that the global pool of free IPv4 addresses was emptied in February 2011. APNIC, which distributes IP addresses in the Asia-Pacific region, ran out of IPv4 addresses in May 2011; it has been working under the "final /8" regime ever since. The remaining three Regional Internet Registries are AfriNIC (Africa), LACNIC (Latin America and the Caribbean), and ARIN (North America), which all have enough IPv4 addresses to last at least two more years. Since the depletion of IPv4 address space in the APNIC region, little information has surfaced about how network operators in the region have managed the situation. However, the lack of IPv4 addresses only impacts organizations and consumers who need additional addresses, or who need addresses for the first time. Existing IPv4 users remain unaffected, and so the immediate impact is limited. Also, large network operators get large address blocks from the RIRs and they typically have a pool of unused addresses of their own, so few will be experiencing immediate problems. However, every year for the past five years, some 200 million new IPv4 addresses have been put into use. Without a steady supply of fresh addresses, many Internet-related activities are going to become problematic in the years to come. Fortunately, 20 years ago the Internet Engineering Task Force (IETF) foresaw that the 3.7 billion addresses afforded by the 32-bit IPv4 address space would become a problem, and started working on a replacement: IPv6. But the IPv4 depletion didn't happen as fast as the IETF originally predicted, and IPv6 adoption has languished. But recently, IPv6 adoption got a big push in the form of World IPv6 Launch. Eventually, IPv6 will replace IPv4, but the transition won't be pretty.
