[liveblog][bkc] Scott Bradner: IANA: Important, but not for what they do"

I’m at a Berkman Klein [twitter: BKCHarvard] talk by Scott Bradner about IANA, the Internet Assigned Names Authority. Scott is one of the people responsible for giving us the Internet. So, thanks for that, Scott!

NOTE: Live-blogging. Getting things wrong. Missing points. Omitting key information. Introducing artificial choppiness. Over-emphasizing small matters. Paraphrasing badly. Not running a spellpchecker. Mangling other people’s ideas and words. You are warned, people.

Scott begins by pointing to the “absurdity” of Ted Cruz’s campaign
to prevent the “Internet giveaway.”“ The idea that “Obama gave away the Internet” is “hooey,”” The idea that “Obama gave away the Internet” is “hooey,” says Scott.

IANA started with a need to coordinate information, not to control it, he says. It began with the Network Working Group in 1968. Then Requests for Comments (RFC) in 1969. . The name “IANA” showed up in 1988, although the function had begun in 1972 with coordinating socket numbers. The Domain Name System made IP addresses easier to use, including the hierarchical clustering under .com, .org, etc.

Back to the beginning, computers were too expensive for every gov’t department to have one. So, ARPA wanted to share large and expensive computers among users. It created a packet-based network, which broke info up into packets that were then transmitted. Packet networking was the idea of Paul Baran at RAND who wanted a system that would survive a nuclear strike, but the aim of that network was to share computers. The packets had enough info to make it to their destinations, but the packet design made “no assumptions about the underlying transport network.” No service guarantees about packets making it through were offered. The Internet is the interconnection of the different networks, including the commercial networks that began showing up in the 1990s.

No one cared about the Net for decades. To the traditional telecom and corporate networking people, it was just a toy—”No quality of service, no guarantees, no security, no one in charge.” IBM thought you couldn’t build a network out of this because their definition of a network — the minimal requirements — was different. “That was great because it meant the regulators ignored us.”

The IANA function went into steady state 1984-1995. It did some allocating of addresses. (When Scott asked Jon Postel for addresses for Harvard, Postel sent him some; Postel was the one-person domain allocation shop.) IANA ran it for the top level domains.

“The Internet has few needs,” Scott says. It’s almost all done through collaboration and agreement. There are no requirements except at a very simple level. The only centralized functions: 1. We have to agree on what the protocol parameters are. Machines have to understand how to read the packet headers. 2. We have to allocate blocks of IP addresses and ASN‘s. 3. We have to have a single DNS, at least for now. IANA handles those three. “Everything else is distributed.” Everything else is collaboration.

In 1993, Network Solutions was given permission to start selling domain names. A domain cost $100 for 2 yrs. There were were about 100M names at that point, which added up to real money. Some countries even started selling off their TLD’s (top level domains), e.g., .tv

IANA dealt with three topics, but DNS was the only one of interest to most people. There was pressure to create new TLDs, which Scott thinks doesn’t solve any real problems. That power was given to ISOC, which set up the International Ad-Hoc Committee in 1996. It set up 7 new TLDs, one of which (.web) caused Image Online Design to sue Postel because they said Postel had promised it to them. The Dept. of Commerce saw that it needed to do something. So they put out an RFC and got 400+ comments. Meanwhile, Postel worked on a plan for institutionalizing the IANA function, which culminated in a conference in Jan 1998. Postel couldn’t go, so Scott presented in his stead.

Shortly after that the Dept of Commerce proposed having a private non-profit coordinate and manage the allocation of the blocks to the registries, manage the file that determines TLDs, and decide which TLDs should exist…the functions of IANA. “There’s no Internet governance here, simply what IANA did.”

There were meetings around the world to discuss this, including one sponsored by the Berkman Center. Many of the people attending were there to discuss Internet governance, which was not the point of the meetings. One person said, “Why are we wasting time talking about TLDs when the Internet is going to destroy countries?” “Most of us thought that was a well-needed vacuum,” says Scott. We didn’t need Internet governance. We were better off without it.

Jon Postel submitted a proposal for an Internet Corporation for Assigned Names and Numbers (ICANN). He died of a heart attack shortly thereafter. The Dept. of Commerce accepted the proposal. In Oct 1998 ICANN had its first board meeting. It was a closed meeting “which anticipated much of what’s wrong with ICANN.”

The Dept of Commerce had oversight over ICANN but its only power was to say yes or no to the file that lists the TLDs and the IP addresses of the nameservers for each of the TLDs.” “That’s the entirety of the control the US govt had over ICANN. “In theory, the Dept of Commerce could have said ‘Take Cuba out of that file,’ but that’s the most ridiculous thing they could have done and most of the world could have ignored them.” The Dept of Commerce never said no to ICANN.

ICANN institutionalizes the IANA. But it also has to deal with trademark issues coming out of domain name registrations, and consults on DNS security issues. “ICANN was formed as a little organization to replace Jon Postel.”

It didn’t stay little. ICANN’s budget went from a few million bucks to over $100M.“ “That’s a lot of money to replace a few competent geeks.”” “That’s a lot of money to replace a few competent geeks.” It’s also approved hundreds of TLDs. The bylaws went from 7,000 words to 37,000 words. “If you need 37,000 words to say what you’re doing, there’s something wrong.”

The world started to change. Many govts see the Net as an intrinsic threat.

  • In Sept. 2001, India, Brazil, and South Africa proposed that the UN undertake governance of the Internet.

  • Oct 2013: After Snowden, the Montevideo Statement on the Future of Internet Cooperation proposing moving away from US govt’s oversight of IANA.

  • Apr. 2014: NetMundial Initiative. “Self-appointed 25-member council to perform internet governance.”

  • Mar. 2014: NTIA announces its intent to transition key domain name functions.

The NTIA proposal was supposed to involve all the stakeholders. But it also said that ICANN should continue to maintain the openness of the Internet…a function that ICANN never had. Openness arises from the technical nature of the Net. NTIA said it wouldn’t accept an inter-governmental solution (like the ITU) because it has to involve all the stakeholders.

So who holds ICANN accountable? They created a community process that is “incredibly strong.” It can change the bylaws, and remove ICAN directors or the entire board.

Meanwhile, the US Congress got bent out of shape because the US is “giving away the Internet.” It blocked the NTIA from acting until Sept. 2016. On Oct. 1 IANA became independent and is under the control of the community. “This cannot be undone.” “If the transition had not happened, forces in the UN would likely have taken over” governance of the Internet. This would have been much more likely if the NTIA had not let it go. “The IANA performs coordination functions, not governance. There is no Internet governance.”

How can there be no governance? “Because nobody cared for long enough that it got away from them,” Scott says. “But is this a problem we have to fix?”

He leaves the answer hanging. [SPOILER: The answer is NO]


Q: Under whom do the IRI‘s [Internationalized Resource Identifier] operate?

A: Some Europeans offered to take over European domain names from Jon Postel. It’s an open question whether they have authority to do what they’re doing Every one has its own policy development process.

Q: Where’s research being done to make a more distributed Internet?

A: There have been many proposals ever since ICANN was formed to have some sort of distributed maintenance of the TLDs. But it always comes down to you seeing the same .com site as I do — the same address pointing to the same site for all Internet users. You still have to centralize or at least distribute the mapping. Some people are looking at geographic addressing, although it doesn’t scale.

Q: Do you think Trump could make the US more like China in terms of the Internet?

A: Trump signed on to Cruz’s position on IANA. The security issue is a big one, very real. The gut reaction to recent DDOS
attacks is to fix that rather than to look at the root cause, which was crappy devices. The Chinese government controls the Net in China by making everyone go through a central, national connection. Most countries don’t do that. OTOH, England is imposing very strict content

rules that all ISPs have to obey. We may be moving to a telephony model, which is a Westphalian
idea of national Internets.

Q: The Net seems to need other things internationally controlled, e.g. buffer bloat. Peer pressure seems to be the only way: you throw people off who disagree.

A: IANA doesn’t have agreements with service providers. Buffer bloat is a real issue but it only affects the people who have it, unlike the IoT DDOS attack that affected us all. Are you going to kick off people who’s home security cameras are insecure?

Q: Russia seems to be taking the opposite approach. It has lots of connections coming into it, perhaps for fear that someone would cut them off. Terrorist groups are cutting cables, botnets, etc.

A: Great question. It’s not clear there’s an answer.

Q: With IPv6 there are many more address spaces to give out. How does that change things?

A: The DNS is an amazing success story. It scales extremely well … although there are scaling issues with the backbone routing systems, which are big and expensive. “That’s one of the issues we wanted to address when we did IPv6.”

Q: You said that ICANN has a spotty history of transparency. What role do you think ICANN is going to play going forward? Can it improve on its track record?

A: I’m not sure that it’s relevant. IANA’s functions are not a governance function. The only thing like a governance issue are the TLDs and ICANN has already blown that.
