cant surf on new ip block

I recently acquired another block of ip addresses and for some reason I am not able to surf when it gives me the address. Any suggestions?

Thanks
Kevin

For starters, please export and post your configuration so we have some idea what you are doing.

Are these your own IP’s or given to you by the ISP?

IF they are your own, have you started advertising them to upstream providers? Have you notified them of the new range so they can adjust their BGP filters both ingress from you and egress to their providers?

Inside or outside og your router.
If its on inside, you need to change address of the inside interface

old

/ip address
add address=192.168.88.1/24 interface=Bridge1 network=192.168.88.0

new

/ip address
add address=192.168.88.1/23 interface=Bridge1 network=192.168.88.0

You may have firewall rules, nat rules, dhcp server, pools and others that need to be change as well.
So post your config.

Check your firewall settings. Or use another IP address. lol
