<p class="MsoNormal">There is nothing wrong with this.<br>
<br>
The fields in the TXT record are concatenated without whitespace in between the fields.<br>
<br>
IPv6 address are case insensitive. If your software crooks on uppercase hex digits, fix it.<br>
<br>
See RFC 7208.<br>
<br>
ip6-network = <as per Section 2.2 of [RFC4291]><br>
; e.g., 2001:db8::cd30<br>
<br>
And if you look at RFC4291 all the examples are is UPPER case.<br>
