How do i delegate i.p addresses ??

[Steve]

Hey guys... I was wondering if i can get a boost from someone.


I have successfully setup a DNS server that resolves  for a small network
and is authorative for a few registered domains.  The name to address
resolutions works ok.  I have read about reverse lookups, but I never went
that far yet. I really didn't think i needed them. 

I also just compiled a new verison of sendmail. I had trouble getting
controlled relaying to work correctly.
I decided that not having reverse look up configured... that I would run
into trouble with others servers like Sendmail. 


I got reverse lookups to resolve successfully locally, but I don't
understand what has to be done for them to work  on the internet.


I got a class C subnet assigned to our network from our provider 
and then I went to signaturedomains.com to register multiple domains.

Do you have to get my ISP to do the delegation or does the registar of my
domain do this ???


HELPFUL INFORMATION :

    DOMAIN NAME : OLAFSOLUTIONS.COM
    Auth. name server :  ns.olafsolutions.com
    
    i.p addresses : 64.244.3.245
                    64.244.3.246
    
  there is more i.p's but they are not being used.


Any help would be appreacited.

Thanks,
Steve
