Re: DNS resolution for hhs.gov

A dig +trace cob.cms.hhs.gov fails for me as it looks like the NS for hhs.gov does not seem to resolve the hostname.

However dig +trace cms.hhs.gov resolves and so does dig +trace eclkc.ohs.acf.hhs.gov

However if I simply ask my local resolver to resolve cob.cms.hhs.gov, it works. Any thoughts on why this is the case?

Looks like their v6 resolvers are failing, but v4 works fine. DNSVis.net is a good place to check nameserver issues.. -- Regards, Robert -- Robert Story USC Information Sciences Institute <http://www.isi.edu/> Networking and Cybersecurity Division
