The social and economic benefits of the Internet cannot be realized without users’ ability to communicate and organize privately, and, where appropriate, anonymously. Data collection warrants must strike a balance to protect these benefits without impeding law enforcement’s ability to enforce the law. In recent weeks, the United States Department of Justice’s (DoJ) conflict with DreamHost, a website hosting service, has underscored the importance of this balance.
A week after the 2017 U.S. presidential inauguration, the DoJ issued a warrant to DreamHost to gather evidence for almost 200 cases related to violence that occurred during Inauguration Day protests. DreamHost had provided services to a website used to coordinate protests during the presidential inauguration.
The initial warrant was broad in scope; DreamHost stated that compliance would mean handing over records relating to 1.3 million IP addresses. This July, the DoJ went even further, issuing a new warrant asking for “Files, databases, and database records” regarding the website in question. DreamHost’s filing with the court specifies that the DoJ sought: the IP addresses of visitors to the website; which website pages were viewed by visitors; and a description of the software running on visitors’ computers.
The DoJ itself appears to Continue reading
Time to market is of essence, because your competitors are already there.
As more and more network engineers dive into network automation, the word idempotence keeps coming up. What is it? Why is it important? Why should we care? Idempotence is often described as the ability to perform the same task repeatedly and produce the same result. I want to demonstrate a super simple example of what this means.
If I am logged into a Linux box and want to add an IP address to the loopback address, I could use something simple like a sed command.
root@leaf01:mgmt-vrf:~# sed -i '/loopback/ a address 1.1.1.1/32' /etc/network/interfaces
This produces exactly what I want!
auto lo
iface lo inet loopback
address 1.1.1.1/32
address 10.0.0.11/32
I have appended the address 1.1.1.1/32 to the loopback interface stanza of the /etc/network/interfaces file. Now what happens if I run that same exact command again?
Running the command again produces the following output:
auto lo
iface lo inet loopback
address 1.1.1.1/32
address 1.1.1.1/32
address 10.0.0.11/32
That is not what I wanted. I performed the same task but instead of just leaving the file alone, since the 1.1.1. Continue reading
Some predict a future where containers and serverless computing will co-exist.
U.S. operators AT&T and Verizon will be responsible for much of the early 5G revenues.
Intel and World Wide Technology launch new NFV testing facility; Barefoot and Cisco do IPv6 segment routing.
Will the VMware-AWS partnership steal the show?

It's VMware's largest-ever telco deal.
RFC 8215 “Local-Use IPv4/IPv6 Translation Prefix” was recently published, reserving the IPv6 prefix 64:ff9b:1::/48 for local use within domains enabling IPv4/IPv6 translation mechanisms.
This allows the coexistence of multiple IPv4/IPv6 translation mechanisms in the same network, without requiring the use of a Network-Specific Prefix assigned from an allocated global unicast address space.
The well-known prefix 64:ff9b::/96 was originally reserved by RFC6052 for IPv4/IPv6 translation, but several new translation mechanisms such as those in RFCs 6146 and 7915 have subsequently been defined that target different use cases. It’s therefore possible that a network operator may wish to make use of several of these simultaneously, hence why a larger address space has been defined to accommodate this.
The shortest translation prefix being deployed in a live network was observed as being a /64, hence /48 was chosen as being on a 16-bit boundary whilst being able to accommodate multiple instances of /64.
If you’re interested in finding out more about IPv4/IPv6 translation mechanisms, there’s a few Deploy360 blogs on NAT64 and 464XLAT amongst others.

Abidjan became the third West African city to hold the annual Africa Peering and Interconnection Forum (AfPIF), attracting top African and global players in the Internet ecosystem.
This year’s forum attracted 227 participants working in IXPs, ISPs, governments, content carriers, network providers, hardware providers, and software service providers among others. The meeting tool, which allows participants to discuss ways to exchange content, had 276 registered users who scheduled 170 meetings. Twenty networks introduced themselves during “Peering Introductions” session, held every day. This year there were 23 sponsors: Seacom, Liquid Telecom, Angonix, Angola Cables, De Cix, Linx, Adva, Afrinic, Akamai, Dolphin, Facebook, Flexoptix, France IX, Google, icolo.io, Main One, Netflix, Netnod, Yahoo, Medalion, MTN, Teraco, and ARTCI.

Research conducted by PCH reinforced the fact that most peering agreements have no formal agreement. The study done in 2016 found that 99 per cent of peering agreements in 148 countries were through a handshake. The study asked questions such as: are there formal agreements, is the peering arrangement symmetrical, is the content is IPv6 or IPv4, and what are the laws governing the agreement. Out of the 1,935,822 agreements, 49 percent comprised of matching peers, meaning it was easy Continue reading
