Your correct hostname is what is displayed on running 'hostname' or 'uname -n' commands. Are you using DNS for hostname resolution? If so, then it is probably a mistake on the DNS server.

nodehostnamesize(5) File Formats Manual nodehostnamesize(5)
NAME
nodehostnamesize - size of node name and host name
DESCRIPTION
The HP-UX operating system default configuration allows the system node name and host name to be up to 8 and 64 bytes in length, respec-
tively. The node name supports the UUCP utilities. The host name supports the internet Domain Name Services (DNS) host name label.
Setting a node name of more than 8 bytes or a host name of more than 64 bytes is possible only with the appropriate configuration options
enabled.
APPLICATION USAGE
See the whitepaper for more information.
WARNINGS
It is strongly recommended that all related documentation be completely understood before setting a larger node or host name. A node name
larger than 8 bytes, or host name larger than 64 bytes, can cause anomalous behavior or failure in applications which use the and/or com-
mands or the and/or system functions to obtain the names.
SEE ALSO
hostname(1), uname(1), uucp(1), setuname(1M), gethostname(2), sethostname(2), uname(2), hostname(5).
