Does anyone use a dns-name which include "_"? Please let me know if yes.
If no, how can stop DDNS to assign a DNS name which include "_"?
Many regards

The underscore has never been a valid character in either host domain
names.
Its in the RFC. A-Z, 0-9 and the hyphen "-" as long as the hyphen is not
the first or last character in the host/domain name.
Underscores started creeping into names when Bill and his evil minions
ignored the RFC and created their own naming schemes.
Cheers,
