Status: Ready for Publication, nits 

Comment: Thank you for a well-written draft.  

The security section provides the necessary warnings for this work.  In
the end, the deployments must implement the security.   The Standard
tools should provide the necessary query mechanisms since you are using
DHCP, DNS Service Discovery, and Anycast.  If implementations have any
syslog or other reporting for systems violating this security, this will
provide was to track this information. 

 In the future, the webrtc - might new syslog and pub/sub work from
NETCONF  (PUSH reports) to report the security errors.   Since it is
upcoming work, I have not suggested it to 

A few editorial nits are below. 

Editorial NIts: 

1) section 3, page 3, paragraph 1, sentence 1

OLD:/ TURN clients, by default, discover TURN servers(s) by means of
local or manual TURN configuration i.e., TURN servers configured at the
system level. 
TURN clients, by default, discover TURN servers(s) by means of local or
manual TURN configuration (i.e., TURN servers configured at the system

2) section 3, page 3-4, 

This sentence is confusing in the "or on top..." clause.  I've suggested
text below - but anything you can do to clarify will satisfy this nit. 

Old/ A client can choose auto-discovery in the absence of local
if the local configuration doesn't work, or on top of local configuration.
New /A client can choose auto-discovery in the absence of local
if the local configuration does work, or choose auto-discovery on top of the
local configuration./
3) section 4.1.1, page 5, paragraph 1, sentence 4

Old /name option; While/ 
new/name option; while/ 

I believe grammar rules will require the second part of the sentence
start without a capital. 

4) section 5 DNS service, page 8, paragraph 3, 

Old/"_turnserver._udp", "_turnserver._tcp". /
New/"_turnserver.udp", or "_turnserver._tcp"/

5) section 9, paragraph 1, sentence 1. 

It might be useful to have STUN reference in this sentence. 

6) page 12 section 9.3, last sentence. 

Your statement on BGP is correct. You do not need to change it. 

Did you want to also include BGP Flow specification filters?
