Question to "Check your understanding #1"

[edit source]

I don't really understand why entries and are not valid for routing tables with CIDR. Host-only routes are allowed in routing tables - like and Of course subnet routes are used much more often, but in some situations it is necessary to add a host route (with mask to direct all the traffic to this address through a different route (e.g. VPN-tunnel). --Sergeyd (discusscontribs) 14:41, 29 October 2013 (UTC)Reply

Question about CIDR

[edit source]

Why is not valid without CIDR? It's class C network, not B, so we can use 3rd byte. If I understood it correctly, we can use only 1st byte of address for A network, 1&2 for B, 1&2&3 for C. --oleamm (discusscontribs) 12:11, 13 February 2014 (UTC)Reply

You are correct, for question 1 , is the valid one without CIDR, and is an invalid network address in Clasfull (without CIDR) -- (discuss) 08:44, 2 December 2015 (UTC)Reply

whole picture of example network

[edit source]

It would be really helpful for learning if we have whole picture of this network, coz in the video it appears for several seconds and it's had to see there ip addresses there. Can you upload it for us if it's possible, please? --Ann Presnyakova (discusscontribs) 20:51, 3 November 2014 (UTC)Reply

Why on the router routing table, for network next hop is, not ? So will receive a data and translate it to other members? Same about ? Typo? Should be 62.206? -- (discuss) 19:07, 9 November 2017 (UTC)Reply

Quiz task1

[edit source]

Should not be accepted without cidr as well since the first 24 bits are the network part? -- (discuss) 13:14, 12 February 2019 (UTC)Reply
