Section 3.3
IPv6 address is 16 octets (bytes) and IPv4 is 4 octets (bytes)
Why the combination of 13 root servers IP4 and IPv6 is 13 * (16 + 28) == 572?
What else you considered in the calculation so that it is 28 octets ?
Presumably
2 octets for a maximally compressed name (as it has already occurred
in the NS RRset)
2 octets for the type
2 octets for the class
4 octets for the TTL
2 octets for the RDATA length field
for a 12-octet overhead. Maybe a reference to RFC 1035 section 3.2.1
is needed to clarify? (although this 12-octet minimum overhead is
rather "well known")
