The domain-name starts with a digit, which is not really recommended, RFC =
1034,
due to the fact a valid actual hostname cannot start with a digit,
and, for example,
some MTAs/MUAs, that comply with earlier versions of standards still in us=
e,
will possibly have a problem sending e-mail to the flat domain, even
if the actual hostname is
something legal such as mail.101100010100110.net.
Which goes back to one of the standard-provided definitions of domain
name syntax used by RFC 821 page 29:
<domain> ::=3D <element> | <element> "." <domain>
<element> ::=3D <name> | "#" <number> | "[" <dotnum> "]"
<mailbox> ::=3D <local-part> "@" <domain>
...
<name> ::=3D <a> <ldh-str> <let-dig>
...
<a> ::=3D any one of the 52 alphabetic characters A through Z
in upper case and a through z in lower case
<d> ::=3D any one of the ten digits 0 through 9
