- [swinog] IPv4 already exhausted at IANA ? –
If you read IANA policies, you know that among the 7 "/8" (some here
will know a /8 as "class A" even though it's incorrect), 5 are
reserved (1 per RIR) and will be allocated when they are the only ones
left. That leaves IANA with only 2 "/8". But APNIC is _already_
entitled to get these addresses, as per IANA policy (they don't have
enough left to hold 9 months at their average alloc rate). And when
they will in reality request these addresses, it will trigger the
allocation of the "last 5", and, well, the end.
It's possible that the IPocalypse is already here.
- IF Map Homepage –
The IF-MAP (Interface to Metadata Access Point) standard enables disparate systems to share information in real time. More specifically, IF-MAP describes how any authorized device or system can publish information to an IF-MAP server, search the server for relevant information, and subscribe to changes to that information. Just as IP revolutionized communications,IF-MAP will revolutionize the way systems share data.
Look slike a cloud orchestration standard. Much overdue, if so.

- Cisco Dynamips and Juniper Olive: A little clarity on router emulators, please – The Network Hub –
Regardless of whether vendors like Juniper and Cisco want to ignore or restrict the use of emulators like Olive and Dynamips, I think the community of networking pros who use these technologies to learn the technology and grow in their careers could benefit from some clarification on this issue. Just tell engineers where they stand. Listen to their request for educational licenses. Don’t let them go on working in this legal gray area.

- VRF Route Leaking –
VPN Routing and Forwarding (VRF) separation is a powerful feature of modern network operating systems, including Cisco IOS that can be used to isolate routing domains and create virtual routers, or routing domains. However, sometimes we need to allow these isolated portions of our network to communicate

- RFC 6106 – IPv6 Router Advertisement Options for DNS Configuration – This document specifies IPv6 Router Advertisement options to allow
IPv6 routers to advertise a list of DNS recursive server addresses
and a DNS Search List to IPv6 hosts.
- Cisco IOS Hints and Tricks: FCoE between data centers? Forget it! –
Was anyone trying to sell you the “wonderful” idea of running FCoE between Data Centers instead of FC-over-DWDM or FCIP? Sounds great … until you figure out it won’t work. Ever … or at least until switch vendors drastically increase interface buffers on the 10GE ports.
Reason 751 to NOT buy FCoE. It doesn't scale.
- ostinato – Project Hosting on Google Code –
Ostinato is an open-source, cross-platform network packet/traffic generator and analyzer with a friendly GUI. Craft and send packets of several streams with different protocols at different rates.
Looks awesome, haven't used it myself, comments please!!
- ISR G2: ISR Harder | The Networking Nerd –
I’m all for upgrades. New hardware makes me drool and faster software with fewer bugs is something everyone can enjoy. But the licensing thing drives me bonkers. I understand the reasons why you have to have it. The pirates and dishonest people out there have seen to it that every slip up or advantage they can use to screw Cisco out of a few dollars are well worth it, no matter what price they might pay. But it also makes the lives of an honest network engin…um, rock star miserable.
We understand Cisco, really we do, but we don't like it. Great review of the x900 routers from Cisco and the 'new' features.
