Addressing plan exercise for our IPv6 course
by Alex Band 30 Jul '10

30 Jul '10

We've been working on an exercise for the IPv6 training course we deliver for LIRs. It's aimed at people who are unfamiliar with IPv6, so the goal is to get them to the point where once they get their IPv6 /32 allocation, they have a good idea how to subdivide prefixes over their network and how to write an addressing plan. Here's a PDF with the exercise (two pages A3): http://bit.ly/c7jZRJ I'm curious to hear if you think it's clear and useful. Cheers, Alex Band RIPE NCC Trainer (Big props go to Marco Hogewoning @XS4ALL)

SingTel (AS7473) is only announcing ConnectPlus (AS9911) routes to Level3 (AS3356) in SJC?
by Martin Barry 30 Jul '10

30 Jul '10

Anyone on the list who can offer an explanation about the following scenario? We have taken this up with providers at either end but it will take awhile to filter up to the ASes in question. We were seeing a London to Singapore connection go via San Jose causing a 50%+ increase in latency. It appears that SingTel (AS7473) is only announcing ConnectPlus (AS9911) routes to Level3 (AS3356) in SJC. However they have many adjacencies in many countries and other routes of both AS7473 and it's other downstreams don't appear to be affected (although I haven't tested them all). Traceroutes are appended at the end but to see for yourself use 202.176.222.0 as a BGP or traceroute query in the Level3 looking glass for both London and any other location, then compare with 167.172.93.0 Checking another large AS at random, they see AS7473 announcing AS9911 routes in London. thanks Marty Show Level 3 (London, England) Traceroute to 202.176.222.212 1 ae-34-52.ebr2.London1.Level3.net (4.69.139.97) 0 msec 0 msec 0 msec 2 ae-42-42.ebr1.NewYork1.Level3.net (4.69.137.70) 68 msec 68 msec ae-41-41.ebr1.NewYork1.Level3.net (4.69.137.66) 72 msec 3 ae-71-71.csw2.NewYork1.Level3.net (4.69.134.70) 68 msec ae-81-81.csw3.NewYork1.Level3.net (4.69.134.74) 72 msec ae-61-61.csw1.NewYork1.Level3.net (4.69.134.66) 76 msec 4 ae-82-82.ebr2.NewYork1.Level3.net (4.69.148.41) 80 msec ae-92-92.ebr2.NewYork1.Level3.net (4.69.148.45) 84 msec ae-72-72.ebr2.NewYork1.Level3.net (4.69.148.37) 80 msec 5 ae-2-2.ebr4.SanJose1.Level3.net (4.69.135.185) 144 msec 144 msec 144 msec 6 ae-74-74.csw2.SanJose1.Level3.net (4.69.134.246) 140 msec ae-94-94.csw4.SanJose1.Level3.net (4.69.134.254) 148 msec ae-64-64.csw1.SanJose1.Level3.net (4.69.134.242) 144 msec 7 ae-12-69.car2.SanJose1.Level3.net (4.68.18.4) 140 msec ae-32-89.car2.SanJose1.Level3.net (4.68.18.132) 140 msec ae-22-79.car2.SanJose1.Level3.net (4.68.18.68) 140 msec 8 SINGAPORE-T.car2.SanJose1.Level3.net (4.79.42.230) 140 msec 140 msec 136 msec 9 POS3-2.sngtp-ar2.ix.singtel.com (203.208.182.205) [AS7473 {APNIC-AS-2-BLOCK}] 148 msec 152 msec 203.208.182.105 [AS7473 {APNIC-AS-2-BLOCK}] 136 msec 10 ge-4-0-0-0.plapx-cr2.ix.singtel.com (203.208.183.173) [AS7473 {APNIC-AS-2-BLOCK}] 148 msec xe-1-0-0-0.plapx-cr3.ix.singtel.com (203.208.183.170) [AS7473 {APNIC-AS-2-BLOCK}] 140 msec 140 msec 11 ge-2-1-0-0.sngtp-dr1.ix.singtel.com (203.208.183.62) [AS7473 {APNIC-AS-2-BLOCK}] 348 msec so-2-0-0-0.sngtp-cr1.ix.singtel.com (203.208.149.181) [AS7473 {APNIC-AS-2-BLOCK}] 336 msec ge-3-0-0-0.sngtp-dr1.ix.singtel.com (203.208.183.66) [AS7473 {APNIC-AS-2-BLOCK}] 360 msec 12 ae0-0.sngtp-cr1.ix.singtel.com (203.208.183.57) [AS7473 {APNIC-AS-2-BLOCK}] 328 msec ge-4-0-0-0.sngtp-cr2.ix.singtel.com (203.208.182.102) [AS7473 {APNIC-AS-2-BLOCK}] 336 msec 202.160.250.226 [AS7473 {APNIC-AS-2-BLOCK}] 336 msec 13 ge-3-0-0-0.sngtp-dr1.ix.singtel.com (203.208.183.66) [AS7473 {APNIC-AS-2-BLOCK}] 348 msec 524 msec 416 msec 14 202.160.250.226 [AS7473 {APNIC-AS-2-BLOCK}] 328 msec 344 msec 203.208.232.234 [AS9911 {APNIC-AS-3-BLOCK}] 336 msec 15 203.208.129.29 [AS9911 {APNIC-AS-3-BLOCK}] 308 msec * 412 msec 16 203.208.232.234 [AS9911 {APNIC-AS-3-BLOCK}] 376 msec * * 17 * * * Show Level 3 (London, England) Traceroute to 167.172.93.1 1 SINGAPORE-T.car1.London1.Level3.net (212.187.160.190) 0 msec 4 msec 0 msec 2 so-0-2-0-0.sngtp-ar6.ix.singtel.com (203.208.151.133) [AS7473 {APNIC-AS-2-BLOCK}] 284 msec 276 msec 276 msec 3 203.208.152.134 [AS7473 {APNIC-AS-2-BLOCK}] 288 msec 284 msec 288 msec 4 ge-5-0-8-0.hkgcw-cr3.ix.singtel.com (203.208.152.37) [AS7473 {APNIC-AS-2-BLOCK}] 276 msec 276 msec ge-5-0-2-0.hkgcw-cr3.ix.singtel.com (203.208.152.117) [AS7473 {APNIC-AS-2-BLOCK}] 284 msec 5 * * * Router: mpr1.lhr1.uk.above.net Command: traceroute 202.176.222.212 traceroute to 202.176.222.212 (202.176.222.212), 30 hops max, 40 byte packets 1 195.66.225.10 (195.66.225.10) 0.991 ms 2.433 ms 0.927 ms 2 so-0-2-0-0.sngtp-ar6.ix.singtel.com (203.208.151.133) 455.799 ms 271.095 ms 254.167 ms 3 203.208.149.210 (203.208.149.210) 255.751 ms 254.794 ms 254.838 ms 4 202.160.250.226 (202.160.250.226) 263.850 ms 263.912 ms 292.504 ms 5 203.208.129.29 (203.208.129.29) 275.109 ms 282.247 ms 313.901 ms 6 203.208.232.234 (203.208.232.234) 265.677 ms 265.604 ms 266.072 ms 7 * * *

33-Bit Addressing via ONE bit or TWO bits ? does NANOG care?
by IPv3.com 30 Jul '10

30 Jul '10

33-Bit Addressing via ONE bit or TWO bits ? does NANOG care? As some people (who understand IPv4) know, there is a SINGLE spare/unused bit in the IPv4 header that can be set to 0 or 1. Some religions require that it be set to 0. Adult content is marked with a 1. That single bit can be viewed as common between the Source and Destination creating a 33rd bit of addressing. Since it is a single bit, it is welded together for both Source and Destination. 0-Normal 1-Evil/Other/Adult/XXX In anticipation of expanding to 33-bit addressing, another bit was deprecated years ago. It can now be used to UNWELD the EVIL bit. That would allow EVIL to be only for the Source. The Destination would have its own EVIL bit. If two bits are used, then the potential to communicate between the previously welded address spaces arises. Some enforcement could still be used in Edge Network Elements to make sure both bits are 0 or both 1. Enforcements are hard to maintain and full 33-bit addressing may emerge. As an aside, NAT was primarily added to improve the .NET Architecture with a Flash Upgrade-able Network Element. It is a shame that IPv6 salesman do not seem to understand "Architecture". They continue on the [NAT is Evil] path. NANOG can play an important role in shaping how Address Plans for North America evolve. Since Network Elements are going to be flash upgraded for the new DNS, it is easy to (unweld/change) the 33-bit addressing for .XXX The 33-bit addressing works into the 66-bit Triple-Tagged VLAN addressing with Content Rating. http://en.wikipedia.org/wiki/IEEE_802.1Q The Locator is 33-bits and the ID is 33-bits. Both are UNIQUE. Both fit in the IPv4 foot-print. The three-ring circus architecture emerges. (((Core)Edge)Fringe) does NANOG care? is NANOG now Fringe ?
