The issue with HostA and HostB not receiving IP addresses from the DHCP server while DHCP snooping is enabled can often be resolved by using the command 'no ip dhcp snooping information option'. This command prevents the DHCP snooping information option from being inserted into DHCP packets, which can sometimes cause issues when relaying DHCP requests. By disabling this insertion, the original DHCP packets are forwarded without any additional options that may interfere with the DHCP process. This should allow the clients to receive IP addresses correctly from the DHCP server.
