The shoc computer should be reachable by an alias containing the telescope name. Usually shoc74in is an alias to shocnawe, and shoc40in is an alias to shocndisbelief. If, e.g. shocndisbelief is mounted on the 74 inch telescope, the alias shoc74in should be changed to point to shocndisbelief.
IT should '''ONLY ''' change the '''CNAME record'''. The '''A records ''' should '''NEVER ''' change. Even if only one of the instruments is being moved to another dome, BOTH records must be switched or DNS resolution will be intermittent. Example of a switched DNS setup: The '''above''' setup was always the '''normal''' setup but now the shocndisbelief machine is in the 1m dome (old 30Inch). The '''shocndisbelief''' will no longer be in the 40Inch and will not move around, only the '''shocnawe''' machine will move between the telescopes. Therefore the setup below is what needs to change when the '''shocnawe''' is moved. '''Instrument switched setup'''

Therefore the setup below is what needs to change when the '''shocnawe''' is moved. Note that the '''shoncaweshocnawe''' now points to '''shoc40in.suth.saao.ac.za'''. If it is configured like this, that means the '''shocnawe''' machine is in the '''40inch'''. When it is moved, '''only''' change the '''40''' to '''74''' like below.:
