Why do some providers require IPv6 /64 PA space to have public whois?
by Constantine A. Murenin 13 Dec '12

Hello, I personally don't understand this policy. I've signed up with hetzner.de, and I'm trying to get IPv6; however, on the supplementary page where the complementary IPv6 /64 subnet can be requested (notice that it's not even a /48, and not even the second, routed, /64), after I change the selection from requesting one additional IPv4 address to requesting the IPv6 /64 subnet (they offer no other IPv6 options in that menu), they use DOM to remove the IP address justification field ("Purpose of use"), and instead statically show my name, physical street address (including the apartment number), email address and phone number, and ask to confirm that all of this information can be submitted to RIPE. They offer no option of modifying any of this; they also offer no option of hiding the street address and showing it as "Private Address" instead; they also offer no option of providing contact information different from the contact details for the main profile or keeping a separate set of contact details in the main profile specifically for RIPE; they also offer no option of providing a RIPE handle instead (dunno if one can be registered with a "Private Address" address, showing only city/state/country and postal code; I do know that with ARIN and PA IPv4 subnets you can do "Private Address" in the Address field); they also don't let you submit the form unless you agree for the information shown to be passed along to RIPE for getting IPv6 connectivity (again, no IPv6 is provided by default or otherwise). Is this what we're going towards? No probable cause and no court orders for obtaining individually identifying information about internet customers with IPv6 addresses? In the future, will the copyright trolls be getting this information directly from public whois, bypassing the internet provider abuse teams and even the most minimal court supervision? Is this really the disadvantage of IPv4 that IPv6 proudly fixes? I certainly have never heard of whois entries for /32 IPv4 address allocations! Anyhow, just one more provider where it's easier to use HE's tunnelbroker.net instead of obtaining IPv6 natively; due to the data-mining and privacy concerns now. What's the point of native IPv6 connectivity again? In hetzner.de terms, tunnelbroker.net even provides you with the failover IPv6 address(es), something that they themselves only offer for IPv4! Is it just me, or are there a lot of other folks who use tunnelbroker.net even when their ISP offers native IPv6 support? Might be interesting for HE.net to make some kind of a study. :-) Cheers, Constantine.

Chuck, If you look at the communities on 68.115.27.0/24 you will see 7018:5000. That community means AS209 is a AT&T peering partner. > route-server>sh ip bgp 68.115.217.201 > BGP routing table entry for 68.115.217.0/24, version 13683280 > Paths: (18 available, best #7, table Default-IP-Routing-Table) > Not advertised to any peer > ... > 7018 209 20115, (aggregated by 20115 96.34.212.29), (received & used) > 12.123.1.236 from 12.123.1.236 (12.123.1.236) > Origin IGP, localpref 100, valid, external, atomic-aggregate, best > Community: 7018:5000 7018:37232 Now if you look at results for 75.77.38.0/23 you will see 7018:2000. That would mean AS7029 is an AT&T customer. > route-server>sh ip bgp 75.77.38.0 > BGP routing table entry for 75.77.38.0/23, version 26960376 > Paths: (19 available, best #7, table Default-IP-Routing-Table) > Not advertised to any peer > 7018 7029 26296 26296 26296, (received & used) > 12.123.1.236 from 12.123.1.236 (12.123.1.236) > Origin IGP, localpref 100, valid, external, best > Community: 7018:2000 7018:34011 In AT&T's network, I believe they apply local pref 80 for peer routes and local pref 100 for customer routes. Ignore the local pref values you see on the route server. Let's look at what appears to be going on. Per your earlier post, you verified Charter(AS20115) has the prefix. Charter does not appear to have a interconnect with AT&T(7018) so they send to Centurlink/Qwest(AS209). We see Centurylink(AS209) accepts per their looking glass at https://kai04.centurylink.com/PtapRpts/Public/BackboneReport.aspx. BGP routing table entry for 75.77.38.0/23 20115 26296 Nexthop 205.171.0.93 (via 207.109.19.150) from chi-core-01 (205.171.0.144) Origin IGP, metric 0, localpref 100, internal, valid Last update: 13:30:09 ago Communities: 209:209 209:14520 20115:3200 20115:63004 Originator Id: 205.171.0.93 Cluster ID List: 207.109.19.145 205.171.0.149 Now Centurylink(AS209), sends the /23 to their peer AT&T(AS7018). AT&T accepts the /23 from Centurylink. Since Centurylink is their peer, AT&T assigns local pref 80. That's lower than the 100 assigned to the Windstream. Highest local pref wins. Your prepends are never part of the decision. So AT&T continues to pref the path via their customer Windstream(AS7029). I suspect this is really your problem instead of route registry data. Hopefully, Windstream offers their customers some BGP communities to allow traffic engineering. Finally, the WISP has a AS number from ARIN, they should be able to create their own maintainer on rr.arin.net. The RADB fee might be a little much for your WISP. https://www.arin.net/resources/routing/ Make sense?

RADB entry
by Chuck Church 12 Dec '12

12 Dec '12

Anyone, Hopefully this is a simple question about RADB. I'm supporting a small wireless ISP, they just recently added a second upstream connection - Charter (AS 20115). The IP space was originally issued by the other upstream Windstream (AS 7029). Looking at a few resources such as the bgp.he.net to see who peers with who and looking glasses, it seems that not all of AS 20115 peers are accepting our prefix. AT&T is an example - AS7018. In one case, it's an upstream 2 levels up - Century Link accepts from Charter, but Level 3 doesn't accept it from Century Link. Charter uses RADB. The entry for the prefix looks like this: route: 75.77.38.0/23 descr: Vybrent_Communications AS26296 origin: AS20115 mnt-by: MAINT-CHTR-WD changed: x(a)chartercom.com 20121207 #18:55:23Z source: RADB route: 75.77.38.0/23 descr: Community Connect LLC remarks: Proxy Registered Customer Route remarks: SWIP from NUVOX origin: AS26296 member-of: RS-NUVOX-CUSTOMERS-NONRIR mnt-by: MAINT-AS11456 changed: x(a)nuvox.com 20080519 source: RADB 75.77.38.0/23 is our prefix. Our AS is 26296. Does that entry look right? I'm wondering if the 'origin' AS in the Charter entry is correct, since that is Charter's AS, not ours. To avoid confusion, Nuvox is the ISP that Windstream bought out, hence the name change. Vybrent and Community Connect are the same company by the way as well. Other than RADB, are there any other database registries that should be checked to make sure the info is right? Thanks, Chuck

Windstream appears to be a customer of Level3. Level3 will put a higher local pref on customer routes.

Hello. We are seeing approx. 3% - 10% packet loss between a fixed address on the Cogent network and services on the Comcast network in the SF Bay Area. Are we alone in this?
