Jean-Michel,
to be sure the documentation of that storage would be needed. But my
educated guess is:
select get_byte(decode(substring('52e1fcb6',1,2),'hex'),0)||'.'||
get_byte(decode(substring('52e1fcb6',3,2),'hex'),0)||'.'||
get_byte(decode(substring('52e1fcb6',5,2),'hex'),0)||'.'||
get_byte(decode(substring('52e1fcb6',7,2),'hex'),0)
of course translated to:
select get_byte(decode(substring("columname",1,2),'hex'),0)||'.'||
get_byte(decode(substring("columname",3,2),'hex'),0)||'.'||
get_byte(decode(substring("columname",5,2),'hex'),0)||'.'||
get_byte(decode(substring("columname",7,2),'hex'),0) from yourtable
where "columname" is the name of the column with the IPs.
Best wishes,
Harald
