No. Those are the nameservers for your domain.
If you can resolve contribs.org to 207.182.33.10 then you don't have a DNS problem.
If you can tracert to 207.182.33.10 from one network but not another one then you have a routing problem.
As posted above, you need to get Telstra on the phone and get them to do tracerts and see that there is a problem. They need to sort it out at a level that you are really remote from.
I recommend that you look for a proxy server that lets you connect to Contribs and then start using your static IP - presumably you need the IP for webmail and stuff, and contribs for news and updates.
If you can persuade telstra to give you a different static IP then go for it.
I manage a site in Melbourne on 61.9.145.xxx and one in Sydney on 144.131.132.xxx that can both get to contribs.org. (I don't think it can be your hardware - but I'm using NetComm routers in bridge mode with PPPoE)

Actually, looking at this last short trace, it occurs to me that you possibly should be going out via 61.9.128.251 not 61.9.128.250 - which again is down to Telstra.
I know they're a nightmare to deal with - I came over there for a few weeks in February/early March to configure two sites to connect back to the UK and had a horrible time getting static IP addresses configured - not with the technical stuff, but with their administration. In fact, I think they have still to switch the billing for the Sydney IP from my personal credit card onto the main phone bill ... its only been 8 weeks .....
