ccTLD Name Server Delegation Report Card (10/20/2003)

This report gives a score for each of the ccTLDs based on various checks done on the specified name servers for the ccTLD.

Methodology

Each ccTLD starts out with 0 points. Points are then gained or lost based on the criteria, much of which is found in BCP40[1]. Then the criteria are applied to modify the score, and the sum determines the final grade.

Scoring

+2 Geographic Distribution - BCP 40 Sect 2.5

+2 4+ Name Servers (active)

+1 6+ Name Servers (active)

+1 Zone serials match, consistently

+1 Frequent Updates (3+ a day)

-2 Each lame delegation (or consistent timeouts) BCP 40 Sect 2.[456]

-2 <3 Name Servers

-1 2+ Serial mismatches (per day)

-2 NS RR mismatch ('.' zone vs. TLD zone)

-1 Each recursion available - BCP 40 Sect 2.5

-2 Any allows AXFR

Research Data

The findings presented here were taken from analyzing data realized through automated DNS queries done over time, as found here. Some manual checks were performed for certain tests. For instance, the NS RR mismatch test was done by hand, although I've since found out about an automated one.

Findings & Conclusions

In the root zone, there are...

118 lame (not-working) nameservers in the root zone - nearly 10%.
Approximately 257 unique nameservers with recursion enabled.
Approximate 724 unique A records
1288 total A records. (Why so many duplicated A records?)
1276 NS records

Certain commonly used nameservers have apparent problems...

ns.ripe.net is allowing zone transfers for many zones (gn,lb,lr,mc,mn,nc,ne,np,pe,sd,sg,sn,sv,sz,tf,th,tp,tr,tz,vi,zm) and is lame for (bn,cf,cm,lr,lv,na,om,th)
ns.uu.net is lame for (bw,fi,in,tr,ua,um)
ns.eu.net is lame for (al,ao,ba,ee,pg,tn,tp)
sunic.sunet.se is also allowing them for many zones (bg,bm,ls,ro,sk)
DNS01.REGISTRYADVANTAGE.COM is lame for (gs,ms,tc,tf,vg)
B.ROOT-SERVERS.NET, C.ROOT-SERVERS.NET, F.ROOT-SERVERS.NET - all allow a zone transfer of the root zone - hopefully this matter cannot be exploited in a denial-of-service attack!

Recommendations for Operators

For operators of ccTLD registries, the scoring grid for their particular country code should provide the clues as to what should be addressed and what should be left alone. Operators should ensure that they are listing a minimum of 3 name servers in the root zone. These nameservers should match the NS records listed in the ccTLD zone. In the best case, none of the published nameservers should allow anonymous zone transfers or offer recursion to anonymous client resolvers. Server should be distributed geographically for redundancy in case of localized outages. Finally, all of them should be consistently available and authoritative for the zone in question. For more guidance, please refer to the references and resources section. For questions or clarifications of the findings shown here, or remediation recommendations can be addressed to cctld-questions@credentia.cc.

Notes

For transfer tests, I chose two name servers to test against, so the test was not definitive. The command used was dig to. axfr @name.server.tld. For NS mismatch tests, I used dig +trace to. ns. Some of the scores above are -, which means the test didn't apply or could not be used, as was the case with TLDs that had no active servers or all were lame. Some delegation is being done to UltraDNS name servers, which I have come to learn are using anycast to distribute the queries geographically, so those TLDs have a falsely lower score than they "should" have.
