Centralized NOC Monitoring Solutions
by Eric Cables 06 Mar '12

06 Mar '12

I am evaluating outsourced NOC solutions, where all of the device monitoring and pro-active response is handled by a centralized NOC (NaaS? :-)). The goal is to reduce the day-to-day overhead of calling carriers to troubleshoot circuit problems, basic network troubleshooting when congestion occurs, pro-active response and notification when critical systems go down during off hours, etc. The focus is network related to start, but could branch out into servers in the future. Any feedback on: companies used, what to look for, and general thoughts on a centralized NOC approach would be appreciated. -- Eric Cables

Spread Spectrum NANOG Operational Alert - Source Addresses with 240 to 255
by Guru NANOG 06 Mar '12

06 Mar '12

Adding four more bits to the Left of the Source Address and setting those bits to 1111 (0xF) can help to start the migration to "Regions" and more IPv4 Addresses - Using and Re-Using legacy spectrum <spectrumhttp://www.iana.org/assignments/ipv4-address-space/ipv4-address-spa…>. The real Source Address is shifted 4 bits to the Right. The bits shifted off are placed in the Deprecated TOS field in the DDDD bits. The new TOS field has the SSSS.DDDD for the CPE. If a router attempts to reply or return to the Source Address it will hit one of the Regional Hubs. There are 16 of those. Agile CPE can reply in other ways to the Agile CPE that sent the Source Address with the 1111 bits. NANOG operators may want to study the evolution of 6to4 (2002:IPv4:0000) to 6RD (IPv4:IPv4) which tunnels using Re-Used legacy 32-bit addresses. The Legacy 32-bit Address Space will likely be around a long long time and be reused in many ways. That may increase the market value of /8s. Brokers are now selling /8s on the open market. http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.txt <spectrumhttp://www.iana.org/assignments/ipv4-address-space/ipv4-address-spa…> 16 /8s for "Future use" - it looks like the "Future" has arrived 240/8 Future use 1981-09 RESERVED [15] ... 255/8 Future use 1981-09 RESERVED [15] http://tools.ietf.org/html/draft-gundavelli-v6ops-community-wifi-svcs <http://tools.ietf.org/html/draft-gundavelli-v6ops-community-wifi-svcs-014.13.> 014.13. <http://tools.ietf.org/html/draft-gundavelli-v6ops-community-wifi-svcs-014.13.> Overlapping IPv4 Address Support Wi-Fi Service Provider may segment the network into regions. Two regions may use overlap IPv4 address space. This is particularly important when the Internet is transitioning to IPv6. The Wi-Fi SP may not have enough unique public IPv4 addresses to globally address large number of Wi-Fi device.

AS209/CenturyLink NOC email?
by Jason Lixfeld 06 Mar '12

06 Mar '12

Anyone from AS209/CentryLink around to troubleshoot some routing weirdness? If not, anyone have a NOC email address for them? Google-fu and RADB searches came up empty. Thanks in advance.

https://www.iana.org/domains/root/db/na.html Namibian Network Information Center PO Box 1342 Swakopmund Namibia This gets confusing for the new Top Level Domains http://NA.NOG http://NANOG.GURU What happened to NEW.NOG ? There are only 256 members of NANOG ? http://www.nanog.org/membership_main.html#list Could (Does) each member *manage* a /8 ? http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.txt Many /8s are not used and many others are wasted. Why is that ? Are people really paid $400,000 per year to manage that list ?

Re: Global Naps?

Seems some carriers ignored the fact GNAPs was shutting down and are still trying route calls to them which then causes a serious post dial delay while route advancing is taking place. I hope some carriers read this thread and check their routing.

Evil Bit and Spread Spectrum IP Addressing - NANOG Source Address Shaping
by Guru NANOG 05 Mar '12

05 Mar '12

Common Misconception: One additional bit of IPv4 Addressing will solve world hunger The Evil Bit (or spare unused bit) can be used to store (restore) one bit The Left-Most bit of the 32-bit Source Address Field can be SET to Zero no matter what the original value. The Evil bit can be set IFF the Left-Most bit is **changed**. Setting the Left-Most bit to zero **folds** this table in half. http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.txt Setting the Left-Most bit to ONE would move return traffic to the upper half of the Spectrum which has vast quantities of unused /8s Wide-spread consensus shows that TWO bits can work. Three bits folds the table to 1/8th. Governments want a 4-bit Return Prefix to their Super-Hubs for IPv6-like intercept. The U.S.FCC is expected to issue the regulations on how Spread Spectrum Source Address Shaping will work in their licensed CPE wireless devices. There are 160-bits in the deprecated header so there are many ways to go. One-Way Broadcast IP Addressing is now available. The Source Address Field is used for the second half of the 64-bit Destination Address. The DF (Did Flip) bit near the Evil Bit is used to note the two halves of the Destination Address have been *flipped*. NANOGers simply route 32 and then 32 after the flip based only on the Destination Field. There is no Source Address, only a channel (port). Keywords: WRT DNSMASQ Tomato WIFI Linux CPE
