Re: [HTCondor-devel] ClassAd attributes containing "my" address

[Dan Bradley <dan@xxxxxxxxxxxx>]

Hi Alan,

My memory is that these attributes are all singularly sinful.  When 
ConvertDefaultIPToSocketIP was written, the Sinful class did not yet 
exist.  It does sound like a good idea to employ it.  Even better would 
be to get rid of the need for ConvertDefaultIPToSocketIP, but c'est la vie.
