Also, you can't be certain to get all the ip's by doing domain lookup as some may not be included. I understand you want to restrict access to where you're likely to connect? Networks are delegated by IANA and local registries. Some are then delegated to national registries or directly to major corps. Major corps and regional registries can be found here: http://www.iana.org/assignments/ipv4-address-space but this only lists /8 netblocks. >From each regional registry, you can download lists of the delegated network addresses. For the Dom. Rep. you should find your self under ARIN (www.arin.net), which includes US, ftp://ftp.arin.net/pub/stats/arin/delegated-arin-latest however, this doesn't show to whom it has been delageted. In the end, combining the different info should help you: You know one ip, check which block it belongs to that have been assigned by ARIN and use whois to verify.
