Subnetting question

MrXpert

I was given a subnetting question which was 49.210.83.249/29(ip of host) and worked out that the subnet this is on is 49.210.83.248 with a broadcast address of 49.210.83.255.

I then thought i'd extrapolate on the question and try to calculate the next subnet after this, along with its associated broadcast and range.

I worked it out as
49.211.0.0 subnet
49.211.0.7 broadcast
49.211.0.1 to 49.211.0.6

can anyone confirm it or give me an idea where i went wrong please?

i tried checking it with a calculator but couldn't find any that would generate a whole list of subnets one after the other to find the next one after the 49.210.83.248 subnet. The best i found was solar winds program but i tried generating the list but as there's over 2000000 subnets it was taking a long time.I waited about 10 minutes then gave up as i was no where near the end of the list.

Well since it's a Class A it has a TON of possible subnets..

I don't think the next subnet after 49.210.83.248 /29 would be 49.211.0.0 /29... going to 211 in the second octet would assume you exhausted all the possibilities in the 3rd and 4th octets.

I believe the next subnet would simply be 49.210.84.0 /29
with range: .1 - .6 in the last octet, and broadcast of .7...
and then the next subnet would be 49.210.84.8/29.. and after exhausting all the subnets in the 4th octet you'd once again just increment the 3rd octet to 85 and repeat filling up the 4th octet

thanks for your help with this.
