RFC952:

  1. A "name" (Net, Host, Gateway, or Domain name) is a text string up
   to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus
   sign (-), and period (.). Note that periods are only allowed when
   they serve to delimit components of "domain style names". (See
   RFC-921, "Domain Name System Implementation Schedule", for
   background). No blank or space characters are permitted as part of a
   name. No distinction is made between upper and lower case. The first
   character must be an alpha character. The last character must not be
   a minus sign or period. A host which serves as a GATEWAY should have
   "-GATEWAY" or "-GW" as part of its name. Hosts which do not serve as
   Internet gateways should not use "-GATEWAY" and "-GW" as part of
   their names. A host which is a TAC should have "-TAC" as the last
   part of its host name, if it is a DoD host. Single character names
   or nicknames are not allowed.

Sorry, but you will have to change the hostname if you think standards are
useful. Squid can be configured to cheat but also DNS-servers might reject
this. Bind8.x rejects this (normally) if you have this in your configuration.
Bind will not accept this zone. Also a secondary bind8.x will not accept this
behaviour from the "master" so in fact you are not doing yourself a vafour if
you don't change the name.

(I admit this is not easy to find in the stack of RFC's but now you know...)
