IPv6 allocations to downwards machine with just one /64

Anurag Bhatia
One of my friend went for a VM with a German hosting provider. He got single IPv4 (quite common) and a /64 IPv6. Overall /64 per VM/end server used to be ok till few years back but now these days running applications inside LXC containers (OS level virtualization) make more sense. This gives option to maintain separate hosting environment for each application. I personally do that a lot and infect blog which you are reading right now itself is on a LXC container.

Host a RIPE Atlas probe!

Anurag Bhatia
RIPE NCC is running an excellent project called RIPE Atlas from few years. This is one of largest distributed network measurement projects where thousands of users host small devices called RIPE Atlas Probes on their networks, home connections, datacenters etc. These probes do measurement under both public and private category and make that data available publicly for use by network engineers and helps in optimizing routing. This page shows detailed coverage statistics of the probes.

Vyatta based VyOS - Linux based network OS

Anurag Bhatia
VyOS is quite interesting OS. It’s a open source Linux based network operating system based on Vyatta. It’s config style seems bit like JunOS in terms of hierarchy and set/edit/delete options while editing configuration. **Can one use it in a small ISP or a Corporate LAN setup? Someone asked me recently if we can have complete open source based router in smaller network doing basic stuff. Not with not-so-streamlined Linux shell but networking OS where network engineers favorite tool “?

Last mile broadband technology for PRESENT!

Anurag Bhatia
Came across this impressive cover of last mile broadband issues in Orcas Island in Washington state in Arstechnica.com. It’s very true on how so many areas are just not served and likely will never be served because when you have large telecom players bidding for billion dollar worth of Spectrum, all they care next for is very high value returns. And if they do not see those kind of returns, areas stay unserved.

Night fun task: OpenVPN, Quagga, Rasberry Pi and more!

Anurag Bhatia
I have been using OpenVPN from quite sometime and very much like it. Earlier I was running OpenVPN client on TP Link 1043nd router and that worked great. But recently I switched home routing to Microtik Map2N which has much better VLAN & IPv6 support. Since then I had trouble in getting VPN back live. I can always use VPN client on laptop but that’s ugly for daily use specially when this is my primary work location!
