Re: Port independent web services

[Keith Moore <moore@xxxxxxxxxxxxxxxxxxxx>]

I was thinking about what bugs me about trying to make SRV, or 
NAPTR+SRV, apply to all protocols.

In addition to this being merely a potentially disruptive, incompatible 
change, that doesn't take into account subtle differences in the way 
different protocols use ports,
it would also have a disruptive effect on internal network 
administration and politics of countless organizations. Specifically it 
would give enterprise top-level DNS administrators even more power than 
they have now, for better or (more often I suspect) for worse.

(I'm still remembering a case in which company A divested company B from 
itself, and the new company B's marketing people decided to redo the 
company's web site, and told the IT people to replace ALL of the 
company's DNS records (including NS) with a new set of records, that 
wiped out every single web service that the company's products depended 
on working...  And yes, the marketing people and the C*s who enabled 
them were incompetent beyond measure, but incompetence is part of the 
human condition.  And how DNS needs to work is surprisingly subtle and 
invisible even to most computer people.    And DNS as currently defined, 
or implemented by most service providers, arguably doesn't have the kind 
of access control that's needed for organizations in all of their 
complexity.)
