ISP License in the USA?
by Lorell Hathcock 06 Jun '16

06 Jun '16

NANOG: Our owner has hired a consultant who insists that we should have an ISP license to operate in the United States. (Like they have in other countries like Germany and in Africa where he has extensive personal experience.) I am asking him to tell me which license we should have because I don't know of a license that we are required to have to route IP traffic to end customers. I am familiar with CLEC status filed with our state. But it is not a requirement to pass traffic. He is suggesting COALS with which I am completely unfamiliar. Can anyone tell me if there is a Texas state and/or USA Federal license for a small operator to pass IP traffic from the internet to end users (commercial and/or residential). I am aware that there are some CALEA requirements of ISPs that seem to kick in once a CALEA request is made, but is that different from a license. Thanks, Lorell Hathcock

rfc 1812 third party address on traceroute
by Randy Bush 06 Jun '16

06 Jun '16

rfc1812 says 4.3.2.4 ICMP Message Source Address Except where this document specifies otherwise, the IP source address in an ICMP message originated by the router MUST be one of the IP addresses associated with the physical interface over which the ICMP message is transmitted. If the interface has no IP addresses associated with it, the router's router-id (see Section [5.2.5]) is used instead. some folk have interpreted this to mean that, if a router R has three interfaces .-----------------. | | | B |--------- D S ---------| A R | | C |--------- (toward S) | | `-----------------' if the source of a traceroute from S toward D with TTL to expire on R, and R's FIB wants to exit via C to get back to S (yes, virginia, the internet is highly asymmetric), the source address of the time exceeded message should be C. of course, simpletons such as i would desire the source of the time exceeded message to be A. after all, this is the interface to which i sent the icmp with the TTL to expire. ras's preso, https://www.nanog.org/meetings/nanog47/presentations/Sunday/RAS_Traceroute_… page 10 illustrates this issue with rfc1812 cursory research and talking with C & J seem to indicate that they do what i want not what some folk have interpreted 1812 to mean. at least on some models. is anyone seeing the dreaded rfc1812 behavior in a citable fashion? how common is it? randy

Correct but it needs a lot to do that. We do the geo thing. I didn't want us to and we didn't for a few years but once the geo people had convinced rights owners it was a viable thing they forced people buying their content to use it. I tried to stop it here and failed but it's never over, people are starting to realise it's silly to annoy people who want your services, you just need to find a way to allow them To be fair to Netflix the tunnel blocking will likely have been driven by their content suppliers asserting their contractual rights to not allow access from certain places. Their content suppliers will have seen people boasting how they use tunnels to get round them and tunnel suppliers advertising their services for doing so. Blame them for the blocking as while it was a personal thing they wouldn't have been bothered much. As usual a few people see an opportunity to make money off something and in the process break it for everyone btw the list of tunnel providers was likely supplied by the same geo ip people, some sell that as an extra. brandon

Vidéotron CPE bug
by Simon Perreault 03 Jun '16

Any Vidéotron engineer listening? On your CPE there's a SIP ALG on TCP port 5060 that is causing issues to our clients with Cisco 79xx phones. I'm referring to the CPE that is used for business subscribers with static IP addresses. Please contact me for all the details. Thanks, Simon

Tracking traffic usage at router or switch port?
by Jason Lee 01 Jun '16

01 Jun '16

NANOG Community, Typically where would you expect a service provider to monitor bandwidth usage on your circuits? On the physical switch port interface or on the vlan interface at the router? In some of the field testing I've been doing there can be a difference in the bandwidth usage on the vlan interface at the router vs the physical switch port. Is there any particular reason for using one vs the other? Is there an industry best practice for this? Thanks, Jason

Public DNS64
by Tim Durack 01 Jun '16

01 Jun '16

Anyone know of a reliable public DNS64 service? Would be cool if Google added a Public DNS64 service, then I could point the NAT64 prefix at appropriately placed boxes in my network. Why? Other people are better than me at running DNS resolvers :-) -- Tim:>
