[Tech] Changing Reverse DNS for GRP IP

[Daniel Melnechuk]

Currently our IP address reverse lookup gets us grp.basespace.net.  
Devon would like to change it to green-rainbow.org so that verizon  
might not black list our server, which seems to make sense.

For some reason, which i can't remember, it was set that way by our  
colocation provider.

I have checked and there appears to be nothing of consequence in  
httpd.conf that would cause any problems.

I have greped all files in /etc and no hits.

I have greped all of postfix config files and no hits that have any  
issues.

Other than apache, Zope, postfix and mailman (which has no lists at  
that name), can anyone think of any other possible problem areas that  
could arise from reassigning our reverse lookup?

What about adding green-rainbow.org as a second reverse lookup for  
our IP? Does anyone think that would be a bad idea? Devon, would that  
not address the verizon issue since then verizon would get two PTR  
records instead of one?

Thoughts anyone before we do this?

Peace,
Dan
