Ready with a couple of nits / editorial clarifications.

This document updates Automatic Multicast Tunneling (AMT) defined by RFC 7450
by defining  DNS Reverse IP AMT Discovery (DRIAD), an extension of the relay
discovery process to use a new DNS resource record named AMTRELAY when
discovering AMT relays for source-specific multicast channels.

Major issues:

Minor issues:

Nits/editorial comments:

1. The reading of 2.4.1 and 2.4.3 seemed to me confusing. 2.4.1 speaks about
'establishing' a connection while 2.4.3 speaks about 'completing' a connection.
Are the two terms equivalent? If so, I would prefer to use only one of them, if
not, some more clarification is necessary.

2. The term 'tier 3 ISP' used in Section 3.1.1 is an 'industry term' that needs
to be defined, either by reference or in text.
